From the Lord comes deliverance.
May your blessing be on your people. Psalm 3:8
David ends his “rant” against his enemies with a prayer of blessing. He acknowledges that God is the deliverer, and even though God’s people will be pursued and persecuted, he asks that the peace and blessing of God will be on their lives.
You probably can’t have too many of those kinds of prayers nor too many people to pray them.
