What Does the Bible Say About Lying?

The Bible treats lying as a serious sin: speaking falsehood in order to deceive contradicts the character of God, who cannot lie (Titus 1:2), and wounds the neighbor we are called to love. At the same time, Scripture records hard cases, such as the Hebrew midwives in Egypt and Rahab, which faithful Christians read in different ways and which a single sentence cannot settle.

What does Scripture forbid, and how far does the prohibition reach?

Among the Ten Commandments is this one: “You shall not bear false witness against your neighbor” (Exodus 20:16). Its immediate focus is testimony before judges, where a false word could cost an innocent person his life. But the Law did not stop at the courtroom. Leviticus 19:11 forbids dealing falsely and lying to one another, and Proverbs 12:22 says that lying lips are an abomination to the Lord, while those who act faithfully are his delight. In Proverbs 6:16-19, a lying tongue and a false witness who breathes out lies appear among the things the Lord hates.

Hebrew uses sheqer (falsehood, deceit) both for the false witness of Exodus 20:16 and for the lying lips of Proverbs 12:22. In Greek, pseudos (lie) appears in Ephesians 4:25, where Paul tells believers to put away falsehood and speak the truth with their neighbor, “for we are members one of another.”

Why does lying weigh so heavily in the Bible?

The deepest reason is not a rule but who God is. Numbers 23:19 says God is not a man, that he should lie, and Hebrews 6:18 says it is impossible for God to lie. Jesus presents himself as the truth (John 14:6). To lie, then, is to walk in the opposite direction from the character of the God to whom we belong, and it eats away at the trust that holds the body of Christ together.

Jesus calls the devil a liar and “the father of lies” (John 8:44), and the first recorded lie is the serpent’s, which contradicted the word of God (Genesis 3:4-5). Lying also kills: false witnesses brought Naboth to his death (1 Kings 21:8-14) and were sought against Jesus himself (Matthew 26:59-60).

Inside the church, the case of Ananias and Sapphira shows the same weight. In Acts 5:1-11, they sell a piece of property and bring only part of the price, presenting it as the whole. Peter tells Ananias that he lied to the Holy Spirit (v. 3), that is, to God (v. 4). Their sin was not keeping back part of the money, which was theirs (v. 4), but staging a generosity that did not exist. Finally, Revelation 21:8 places liars among those who will have their portion in the lake of fire, and 22:15 leaves outside the city everyone who loves and practices falsehood. Many interpreters read these texts as a portrait of those who live in deceit without repentance, not of someone who stumbles and returns to God (1 John 1:9). Whether a believer can lose salvation is a separate discussion, covered in another answer.

Did the Egyptian midwives and Rahab lie to save lives?

Two accounts are often cited to claim that the Bible approves of lying when the motive is good. It is worth reading slowly what the text says and what it leaves unsaid.

In Exodus 1:15-21, Pharaoh orders the Hebrew midwives, Shiphrah and Puah, to kill the newborn boys. They fear God and do not obey. When questioned, they answer that Hebrew women are vigorous and give birth before the midwife arrives (v. 19). The text says God dealt well with the midwives and gave them families, and it names the reason as their fear of God (vv. 17, 20-21). In Joshua 2:1-7, Rahab hides the two Israelite spies on her roof and tells the king’s men that the spies had already left. Hebrews 11:31 lists her among the examples of faith because she welcomed the spies in peace, and James 2:25 stresses that she received them and sent them out another way.

Notice what the texts praise: the midwives’ fear of God, and Rahab’s faith and hospitality. Neither passage evaluates the moral worth of the words themselves. In Exodus 1:19 the narrator does not call the answer a lie, and some read it as false, evasive or partly true. In Joshua 2 the statement about the spies is clearly false, since they were hidden. Faithful Christians read these cases in at least three ways:

• The blessing was for faith and mercy, not for the falsehood. An old tradition, in which Augustine is the best-known voice, holds that every lie is sin, even one told to save a life, and that God honored faith in spite of the failure.
• Deceiving those who want to kill the innocent is not the forbidden false witness. Others argue that the prohibition targets deceiving in order to harm someone who has a right to the truth, and that misleading those who seek to take lives is a different matter.
• The text describes, without approving or condemning. The Bible reports many actions without endorsing them, and the narrator’s silence is neither approval nor censure.

These verses alone do not settle the debate, and it is more honest to say so. What the text shows is that in both accounts the speech in question appears with lives at risk and alongside the fear of God or faith in him (Exodus 1:17 and 21; Joshua 2:9-11). The reading, which is not a biblical datum, is that those who allow some exception tend to limit it to extreme situations like these, not to convenience lies told to escape embarrassment or gain an advantage.

Do half-truths, hypocrisy and silence count?

Lying is not limited to false sentences. Hypocrisy deceives too: 1 John 1:6 says that whoever claims fellowship with God while walking in darkness lies, and 1 John 4:20 calls a liar anyone who says he loves God and hates his brother. Then there is the half-truth. Abraham says that Sarah is his sister (Genesis 20:2); she was in fact his half-sister (v. 12), but the statement served to hide that she was his wife, and King Abimelech rebukes him (vv. 9-10).

Keeping silent, on the other hand, is not the same as lying. Proverbs 11:13 commends the person who keeps a matter entrusted to him. The case of Samuel is more disputed: in 1 Samuel 16:1-5, God tells Samuel to take a heifer and say he has come to sacrifice, because Samuel feared Saul would kill him (v. 2). The text indicates there was a sacrifice to be made (vv. 2-5), but the stated reason concealed the main purpose, the anointing of a new king. Many see legitimate reserve here, since, on that reading, Samuel said nothing false; others see a ruse authorized by God in the face of a threat. The text does not decide. The opposite error exists too: using truth as a weapon. Paul asks us to practice “truth in love” (Ephesians 4:15).

What if I have already lied? The way back

Almost all of us have lied. Peter denied three times that he knew Jesus (Luke 22:54-62) and was restored by the risen Lord (John 21:15-19). The promise of 1 John 1:9 applies here: if we confess our sins, God is faithful and just to forgive. That forgiveness does not come from a flawless life but from Christ’s work on the cross (1 John 1:7).

In practice, this calls for simple steps:

• Avoid the exaggeration that distorts the facts, and the promise you do not intend to keep.
• Admit the mistake instead of inventing an excuse to protect your image.
• Repair the deception with the person who was deceived, whenever that is possible and safe.
• Speak the truth in love, without humiliating and without manipulating.

None of this comes from willpower alone. Jesus said that whoever abides in his word knows the truth, and the truth sets him free (John 8:31-32).
