Jeremiah 9:4-6

4Everyone must be on his guard around his friends. He must not even trust any of his relatives. For every one of them will find some way to cheat him. And all of his friends will tell lies about him.

5One friend deceives another and no one tells the truth. These people have trained themselves to tell lies. They do wrong and are unable to repent.

6They do one act of violence after another, and one deceitful thing after another. They refuse to pay attention to me,” says the Lord.
