Jeremiah 9:3-6

ERV(i) 3 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 the LORD. 4 Take 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. 5 And 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. 6 Thine habitation is in the midst of deceit; through deceit they refuse to know me, saith the LORD.
