Proverbs 6:16-19
16 There are six things which Yahweh hates; Yes, seven which are an abomination to him:
17 Haughty eyes, a lying tongue, Hands that shed innocent blood;
18 A heart that devises wicked schemes, Feet that are swift in running to mischief,
19 A false witness who utters lies, And he who sows discord among brothers.

Jeremiah 9:2-8
2 Oh that I had in the wilderness a lodging-place of wayfaring men; that I might leave my people, and go from them! for they are all adulterers, an assembly of treacherous men.
3 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 don't know me, says Yahweh.
4 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 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 Your habitation is in the midst of deceit; through deceit they refuse to know me, says Yahweh.
7 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?
