Jeremiah 9:4-8

4“Everyone take heed to his neighbor, And do not trust any brother; For every brother will utterly supplant, And every neighbor will walk with slanderers.

5Everyone will deceive his neighbor, And will not speak the truth; They have taught their tongue to speak lies; They weary themselves to commit iniquity.

6Your dwelling place is in the midst of deceit; Through deceit they refuse to know Me,” says the Lord.

7Therefore thus says the Lord of hosts: “Behold, I will refine them and try them; For how shall I deal with the daughter of My people?

8Their tongue is an arrow shot out; It speaks deceit; One speaks peaceably to his neighbor with his mouth, But in his heart he lies in wait.
