Jeremiah 9:2-4

2Oh that I had in the wilderness a traveller's lodging-place, that I might leave my people, and go away from them! For they are all adulterers, an assembly of treacherous men.

3And they bend their tongue, their bow of falsehood, and not for fidelity are they valiant in the land; for they proceed from evil to evil, and they know not me, saith Jehovah.

4Take ye heed every one of his friend, and confide not in any brother; for every brother only supplanteth, and every friend goeth about with slander.
