Jeremiah 9:4-7 World English Bible (WEB)

4. “Everyone beware of his neighbor, and don’t trust in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders.

5. Everyone will deceive their neighbors, and will not speak the truth. They have taught their tongue to speak lies. They weary themselves commiting iniquity.

6. Your habitation is in the middle of deceit; through deceit they refuse to know me,” says Yahweh.

7. Therefore Yahweh of Armies says, “Behold, I will melt them, and try them; for how should I deal with the daughter of my people?
