Jeremiah 9
4 Ref Take you heed everyone of his neighbor, and don't you trust in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders.
5 Ref They will deceive everyone his neighbor, and will not speak the truth: they have taught their tongue to speak lies; they weary themselves to commit iniquity.
6 Ref Your habitation is in the midst of deceit; through deceit they refuse to know me, says Yahweh.
7 Ref Therefore thus says Yahweh of Hosts, Behold, I will melt them, and try them; for how [else] should I do, because of the daughter of my people?
8 Ref Their tongue is a deadly arrow; it speaks deceit: one speaks peaceably to his neighbor with his mouth, but in his heart he lays wait for him.
9 Ref Shall I not visit them for these things? says Yahweh; shall not my soul be avenged on such a nation as this?
