Jeremiah 9:1-4

Oh that my head were waters, and mine eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people! 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. And 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 Jehovah. Take ye heed every one of his neighbor, and trust ye not in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders.
