“There is no truth in their mouth.
Their hearts are destruction.
Their throats are open graves.
They flatter with their tongues.
Make them bear their guilt!
O God!
Let them fall by their own counsels!
Because of their many criminal transgressions,
Cast them out!
They have rebelled against you.”
Now David attacked his enemies, the wicked ones. They were liars. They have cruel destructive hearts. Their throats were like open graves. They flattered everyone. David wanted them to confess and bear their guilt. He wanted vengeance. He wanted them to fall because of their many transgressions. They were to be cast out from the sight of Yahweh. They had rebelled against Yahweh. There was no greater sin than that.
