Jeremiah 9:3-8

3Beware, everyone, of your neighbor! Don’t even trust a brother. For every brother grabs like Jacob and every neighbor spreads slander.

4Everyone deceives his neighbor and does not speak the truth. They taught their tongue to speak lies. They wear themselves out doing wrong.

5“You dwell in the midst of deceit. In deceit they refuse to know Me.” It is a declaration of Adonai.

6Therefore thus says Adonai-Tzva’ot: “I am about to refine them and test them. For what else can I do for the daughter of My people?

7Their tongue is a deadly arrow, speaking deceit. With his mouth each says shalom to his neighbor, while inwardly setting a trap for him.

8For such things shall I not punish them?” It is a declaration of Adonai. “Should I not avenge Myself on such a nation as this?”
