Thematic Bible: David, to his enemies

They reward me evil for good, to the bereavement of my soul. But as for me, when they were sick, my clothing was sackcloth; I chastened my soul with fasting, and my prayer returned into mine own bosom: I behaved myself as though he had been a friend, a brother to me; I bowed down in sadness, as one that mourneth for a mother.
