Jeremiah 9:3-4

3The Lord says, “These people are like soldiers who have readied their bows. Their tongues are always ready to shoot out lies. They have become powerful in the land, but they have not done so by honest means. Indeed, they do one evil thing after another and do not pay attention to me.

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.
