Jeremiah 9:6

3 “They bend their tongue, as their bow, for falsehood. They have grown strong in the land, but not for truth; for they proceed from evil to evil, and they don’t know me,” says the LORD.

4 “Everyone beware of his neighbor, and don’t trust in any brother; for every brother will utterly supplant, and every neighbor will go around like a slanderer.

5 Friends deceive each other, and will not speak the truth. They have taught their tongue to speak lies. They weary themselves committing iniquity.

6 Your habitation is in the middle of deceit. Through deceit, they refuse to know me,” says the LORD.

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

8 Their tongue is a deadly arrow. It speaks deceit. One speaks peaceably to his neighbor with his mouth, but in his heart, he waits to ambush him.

9 Shouldn’t I punish them for these things?” says the LORD. “Shouldn’t my soul be avenged on a nation such as this?
