Jeremiah 9:2-9

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 be all adulterers, an assembly of treacherous men. 3And they bend their tongues like their bow for 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 Yhwh. 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.1 5And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, and weary themselves to commit iniquity.2 6Thine habitation is in the midst of deceit; through deceit they refuse to know me, saith Yhwh. 7Therefore thus saith Yhwh of Armies, Behold, I will melt them, and try them; for how shall I do for the daughter of my people? 8Their tongue is as an arrow shot out; it speaketh deceit: one speaketh peaceably to his neighbour with his mouth, but in heart he layeth his wait.34

9Shall I not visit them for these things? saith Yhwh: shall not my soul be avenged on such a nation as this?
