Jeremiah 9:4-6

4“Beware of your friends; do not trust anyone in your clan. For every one of them is a deceiver, Or a deceiving Jacob and every friend a slanderer.

5Friend deceives friend, and no one speaks the truth. They have taught their tongues to lie; they weary themselves with sinning.

6You That is, Jeremiah (the Hebrew is singular) live in the midst of deception; in their deceit they refuse to acknowledge me,” declares the LORD .
