Jeremiah 9:5
King James Version
“And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, weary themselves to commit iniquity.”
Context
2Oh that I had in the wilderness a lodging place of wayfaring men; that I might leave my people, and go from them! for they all adulterers, an assembly of treacherous men.
3And they bend their tongues their bow lies: but they are not valiant for the truth upon the earth; for they proceed from evil to evil, and they know not me, saith the LORD.
4Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders.
5And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, weary themselves to commit iniquity.
6Thine habitation in the midst of deceit; through deceit they refuse to know me, saith the LORD.
7Therefore thus saith the LORD of hosts, Behold, I will melt them, and try them; for how shall I do for the daughter of my people?
8Their tongue an arrow shot out; it speaketh deceit: speaketh peaceably to his neighbour with his mouth, but in heart he layeth his wait.
