Blasphemy is defined as the act of insulting or showing contempt or lack of reverence for God. The Bible talks about blasphemy in both the Old and New Testaments. Here are some key Bible verses about blasphemy:
Leviticus 24:10-16
This passage in Leviticus tells the story of a man who blasphemes the name of the Lord and curses. God commands that the man be brought outside the camp and stoned to death. This shows how seriously God took blasphemy under the Old Testament law.
And the son of an Israelite woman, whose father was an Egyptian, went out among the people of Israel. And the Israelite woman’s son and a man of Israel fought in the camp, and the Israelite woman’s son blasphemed the Name, and cursed. Then they brought him to Moses. His mother’s name was Shelomith, the daughter of Dibri, of the tribe of Dan. And they put him in custody, till the will of the Lord should be clear to them. Then the Lord spoke to Moses, saying, “Bring out of the camp the one who cursed, and let all who heard him lay their hands on his head, and let all the congregation stone him. And speak to the people of Israel, saying, Whoever curses his God shall bear his sin. Whoever blasphemes the name of the Lord shall surely be put to death. All the congregation shall stone him. The sojourner as well as the native, when he blasphemes the Name, shall be put to death.
Leviticus 24:15-16
This passage emphasizes again that blasphemers were to be put to death under the law of Moses. Blasphemy was not taken lightly.
Say to the Israelites: ‘Anyone who curses their God will be held responsible; anyone who blasphemes the name of the Lord is to be put to death. The entire assembly must stone them. Whether foreigner or native-born, when they blaspheme the Name they are to be put to death.
Mark 3:28-29
Jesus teaches that all sins can be forgiven except blasphemy against the Holy Spirit. Blasphemy against the Spirit is an eternal sin.
Truly, I say to you, all sins will be forgiven the children of man, and whatever blasphemies they utter, but whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin”—for they were saying, “He has an unclean spirit.”
Mark 7:20-23
Jesus teaches that evil words and blasphemies come from the heart. Our words reflect the condition of our hearts.
And he said, “What comes out of a person is what defiles him. For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. All these evil things come from within, and they defile a person.”
John 10:31-39
The Jews tried to stone Jesus for claiming to be God, accusing Him of blasphemy. Jesus responds by affirming His divine identity.
The Jews picked up stones again to stone him. Jesus answered them, “I have shown you many good works from the Father; for which of them are you going to stone me?” The Jews answered him, “It is not for a good work that we are going to stone you but for blasphemy, because you, being a man, make yourself God.” Jesus answered them, “Is it not written in your Law, ‘I said, you are gods’? If he called them gods to whom the word of God came—and Scripture cannot be broken— do you say of him whom the Father consecrated and sent into the world, ‘You are blaspheming,’ because I said, ‘I am the Son of God’? If I am not doing the works of my Father, then do not believe me; but if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me and I am in the Father.” Again they sought to arrest him, but he escaped from their hands.
Matthew 12:31-32
Jesus again emphasizes that blasphemy against the Spirit will not be forgiven. Other sins can be forgiven.
Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven. And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
Luke 12:8-10
Jesus warns that whoever blasphemes against the Holy Spirit will not be forgiven. He compares this to whoever denies Jesus before others.
“And I tell you, everyone who acknowledges me before men, the Son of Man also will acknowledge before the angels of God, but the one who denies me before men will be denied before the angels of God. And everyone who speaks a word against the Son of Man will be forgiven, but the one who blasphemes against the Holy Spirit will not be forgiven.
1 Timothy 1:12-17
Paul shares his gratitude that Christ strengthened him and had mercy on him even though he had formerly been a blasphemer.
I thank him who has given me strength, Christ Jesus our Lord, because he judged me faithful, appointing me to his service, though formerly I was a blasphemer, persecutor, and insolent opponent. But I received mercy because I had acted ignorantly in unbelief, and the grace of our Lord overflowed for me with the faith and love that are in Christ Jesus. The saying is trustworthy and deserving of full acceptance, that Christ Jesus came into the world to save sinners, of whom I am the foremost. But I received mercy for this reason, that in me, as the foremost, Jesus Christ might display his perfect patience as an example to those who were to believe in him for eternal life. To the King of the ages, immortal, invisible, the only God, be honor and glory forever and ever. Amen.
2 Kings 19:1-7
When King Hezekiah hears Sennacherib’s servants blaspheme God, he tears his clothes and cries out to the Lord. God promises deliverance from the blasphemers.
As soon as King Hezekiah heard it, he tore his clothes and covered himself with sackcloth and went into the house of the Lord. And he sent Eliakim, who was over the household, and Shebna the secretary, and the senior priests, covered with sackcloth, to the prophet Isaiah the son of Amoz. They said to him, “Thus says Hezekiah, This day is a day of distress, of rebuke, and of disgrace; children have come to the point of birth, and there is no strength to bring them forth. It may be that the Lord your God heard all the words of the Rabshakeh, whom his master the king of Assyria has sent to mock the living God, and will rebuke the words that the Lord your God has heard; therefore lift up your prayer for the remnant that is left.” When the servants of King Hezekiah came to Isaiah, Isaiah said to them, “Say to your master, ‘Thus says the Lord: Do not be afraid because of the words that you have heard, with which the servants of the king of Assyria have reviled me. Behold, I will put a spirit in him, so that he shall hear a rumor and return to his own land, and I will make him fall by the sword in his own land.’”
2 Chronicles 32:9-22
King Sennacherib blasphemes God by questioning His ability to deliver Jerusalem. In response, God sends an angel to strike down the Assyrian army.
After this, Sennacherib king of Assyria, who was besieging Lachish with all his forces, sent his servants to Jerusalem to Hezekiah king of Judah and to all the people of Judah who were in Jerusalem, saying, “Thus says Sennacherib king of Assyria, ‘On what are you trusting, that you endure the siege in Jerusalem? Is not Hezekiah misleading you, that he may give you over to die by famine and by thirst, when he tells you, “The Lord our God will deliver us from the hand of the king of Assyria”? Has not this same Hezekiah taken away his high places and his altars and commanded Judah and Jerusalem, “Before one altar you shall worship, and on it you shall burn your sacrifices”? Do you not know what I and my fathers have done to all the peoples of other lands? Were the gods of the nations of those lands at all able to deliver their lands out of my hand? Who among all the gods of those nations that my fathers devoted to destruction was able to deliver his people from my hand, that your God should be able to deliver you from my hand? Now, therefore, do not let Hezekiah deceive you or mislead you in this fashion, and do not believe him, for no god of any nation or kingdom has been able to deliver his people from my hand or from the hand of my fathers. How much less will your God deliver you out of my hand!’”
And his servants said still more against the Lord God and against his servant Hezekiah. And he wrote letters to cast contempt on the Lord, the God of Israel, and to speak against him, saying, “Like the gods of the nations of the lands who have not delivered their people from my hands, so the God of Hezekiah will not deliver his people from my hand.” And they shouted it with a loud voice in the language of Judah to the people of Jerusalem who were on the wall, to frighten and terrify them, in order that they might take the city. And they spoke of the God of Jerusalem as they spoke of the gods of the peoples of the earth, which are the work of men’s hands.
Then Hezekiah the king and Isaiah the prophet, the son of Amoz, prayed because of this and cried to heaven. And the Lord sent an angel, who cut off all the mighty warriors and commanders and officers in the camp of the king of Assyria. So he returned with shame of face to his own land. And when he came into the house of his god, some of his own sons struck him down there with the sword. So the Lord saved Hezekiah and the inhabitants of Jerusalem from the hand of Sennacherib king of Assyria and from the hand of all his enemies, and he provided for them on every side.
Psalm 74:10,18,22
The psalmist cries out to God, asking how long the enemy will be allowed to blaspheme and revile God’s name.
How long, O God, is the foe to scoff? How long will the enemy revile your name?
Remember this, O Lord, how the enemy scoffs, and a foolish people reviles your name.
Arise, O God, defend your cause; remember how the foolish scoff at you all the day!
2 Samuel 12:9-14
After David commits adultery with Bathsheba and orchestrates the death of her husband Uriah, the prophet Nathan confronts David about his sin, saying he has given occasion for the enemies of God to blaspheme.
Why have you despised the word of the Lord, to do what is evil in his sight? You have struck down Uriah the Hittite with the sword and have taken his wife to be your wife and have killed him with the sword of the Ammonites. Now therefore the sword shall never depart from your house, because you have despised me and have taken the wife of Uriah the Hittite to be your wife.’ Thus says the Lord, ‘Behold, I will raise up evil against you out of your own house. And I will take your wives before your eyes and give them to your neighbor, and he shall lie with your wives in the sight of this sun. For you did it secretly, but I will do this thing before all Israel and before the sun.’” David said to Nathan, “I have sinned against the Lord.” And Nathan said to David, “The Lord also has put away your sin; you shall not die. Nevertheless, because by this deed you have utterly scorned the Lord, the child who is born to you shall die.”
Isaiah 52:3-5
God promises to deliver Israel from captivity, saying they will no longer suffer the taunts and blasphemies of their enemies.
For thus says the Lord: “You were sold for nothing, and you shall be redeemed without money.” For thus says the Lord God: “My people went down at the first into Egypt to sojourn there, and the Assyrian oppressed them for nothing. Now therefore what have I here,” declares the Lord, “seeing that my people are taken away for nothing? Their rulers wail,” declares the Lord, “and continually all the day my name is despised.
Ezekiel 20:27-28
God accuses Israel of blaspheming Him with their idolatry in Egypt.
“Therefore, son of man, speak to the house of Israel and say to them, Thus says the Lord God: In this also your fathers blasphemed me, by dealing treacherously with me. For when I had brought them into the land that I swore to give them, then wherever they saw any high hill or any leafy tree, there they offered their sacrifices and there they presented the provocation of their offering; there they sent up their pleasing aromas, and there they poured out their drink offerings.
Revelation 13:1,5-6
John sees a vision of a beast rising out of the sea who utters blasphemies against God.
And I saw a beast rising out of the sea, with ten horns and seven heads, with ten diadems on its horns and blasphemous names on its heads.
And the beast was given a mouth uttering haughty and blasphemous words, and it was allowed to exercise authority for forty-two months. It opened its mouth to utter blasphemies against God, blaspheming his name and his dwelling, that is, those who dwell in heaven.
Revelation 17:3
John describes a vision of a woman sitting on a scarlet beast full of blasphemous names.
And he carried me away in the Spirit into a wilderness, and I saw a woman sitting on a scarlet beast that was full of blasphemous names, and it had seven heads and ten horns.
Jude 1:8-13
Jude condemns dreamers who reject authority and blaspheme the glorious ones (likely a reference to angels).
Yet in like manner these people also, relying on their dreams, defile the flesh, reject authority, and blaspheme the glorious ones. But when the archangel Michael, contending with the devil, was disputing about the body of Moses, he did not presume to pronounce a blasphemous judgment, but said, “The Lord rebuke you.” But these people blaspheme all that they do not understand, and they are destroyed by all that they, like unreasoning animals, understand instinctively. Woe to them! For they walked in the way of Cain and abandoned themselves for the sake of gain to Balaam’s error and perished in Korah’s rebellion. These are hidden reefs at your love feasts, as they feast with you without fear, shepherds feeding themselves; waterless clouds, swept along by winds; fruitless trees in late autumn, twice dead, uprooted; wild waves of the sea, casting up the foam of their own shame; wandering stars, for whom the gloom of utter darkness has been reserved forever.
In summary, these verses demonstrate the seriousness of blasphemy according to the Bible. Blasphemy represents a grave offense toward God, dishonoring and showing contempt for Him. The Old Testament prescribed the death penalty for blasphemy. Jesus warned that all manner of sin can be forgiven except unrepentant blasphemy against the Holy Spirit. Blasphemy springs from a sinful, unregenerate heart. God is greatly angered by blasphemy and promises to judge those who revile and mock Him.
