Jeremiah 9:5 describes a society where people no longer trust one another because lying has become a habit. The prophet is saying that deception has become so ordinary that people wear themselves out practicing it, and the damage spreads from individual speech to the entire community. The words come from Jeremiah, the prophet of Judah, who speaks on God’s behalf to the people of Jerusalem in the years before the Babylonian exile.
Everyone will deceive their neighbors, and will not speak the truth. They have taught their tongue to speak lies. They weary themselves commiting iniquity.

What Jeremiah 9:5 Means
The verse begins with “everyone will deceive their neighbors,” which describes a general condition rather than a few bad actors. Jeremiah is not talking about one dishonest merchant or one false witness. He is describing a culture in which suspicion and dishonesty run through ordinary relationships between neighbors, friends, and even family members.
The next phrases speak about the tongue. The prophet says people have trained their tongues to speak lies, as if speech were a skill to be practiced and sharpened. The final image says they weary themselves committing iniquity, meaning sin is so constant that it exhausts them. The verse does not promise that lying will eventually bring peace or reward. It describes the cost of a life built on falsehood, and it implies that such a life is both tiring and destructive.
The Context of Jeremiah 9:5
The book of Jeremiah records the words and ministry of a prophet who served in Jerusalem during the final decades before the city fell to Babylon in 586 BC. Tradition holds that Jeremiah himself is the main source of the book, though it was shaped and arranged over time. His audience was the people of Judah, including religious leaders, royal officials, and common families who had grown comfortable with outward religion while their everyday conduct drifted far from God’s covenant.
Just before verse 5, the Lord describes a people who “bend their tongue, as their bow, for falsehood,” and in verse 4 he warns that no one can trust even a brother or neighbor. Verse 6 then returns to deceit as the very setting in which the people live. Read in this sequence, verse 5 is the center of a sustained indictment. The problem is not only what people say but the broken relationships that lying produces, and the verse shows how that breakdown reveals a people who refuse to know God.
Key Phrases in Jeremiah 9:5
Ephesians 4:25
Therefore putting away falsehood, speak truth each one with his neighbor. For we are members of one another.
(WEB)
Paul builds on the same concern for truthful speech among believers, urging people to put away falsehood because they belong to one another. Where Jeremiah describes a community ruined by lies, Ephesians shows the positive picture of a body held together by honesty.
Proverbs 12:22
Lying lips are an abomination to the LORD, but those who do the truth are his delight.
(WEB)
The book of Proverbs states plainly what Jeremiah implies, that lying is detestable to God while faithfulness brings delight. Reading the two together helps you see that dishonesty is both a personal failing and something God actively opposes.
A Short Prayer From Jeremiah 9:5
Lord, you see the places in my life where I have grown comfortable with half-truths and convenient silences. Search my heart and show me the habits of speech that have been shaping me away from you. Give me courage to speak plainly and kindness to speak carefully, so that my words build trust rather than wear it down. Renew my strength where sin has left me weary, and make my life a place where people can rely on what I say. Amen.
