God is my helper.
Yahweh is the upholder of my life.
He will repay my enemies for their evil.
In your faithfulness
Put an end to them!”
The response of David is to call God to help him. Yahweh was the one who sustained him in his life. He believed that Yahweh would repay his enemies for what they have done. They had not been faithful to Yahweh. He wanted them eliminated, an end to them.
