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 tongue as it were their bow for falsehood; and they are grown strong in the land, but not for truth: 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 go about with slanders.

5And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies; they weary themselves to commit iniquity.

6Thine habitation is 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 else should I do, because of the daughter of my people?

8Their tongue is a deadly arrow; it speaketh deceit: one speaketh peaceably to his neighbour with his mouth, but in his heart he layeth wait for him.

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