In the book of 2 Samuel, chapter 22, is a very long song David sang that one should save for those days when you feel like everyone is against you and you need God's Loving Power to lift you up.
It starts with telling of how the Lord is his rock, his fortress, guiding him in all the battles that came upon him.
He prays for God to give him strength against all of his enemies, those who turns their backs to him, and to crush them like fine sand.
God's Power is awesome for those who worship him.
