41:10 David had asked God to restore his health so he might repay his enemies. This may seem to be an unworthy motive in view of the Lord Jesus' instruction to love our enemies and do them good (Matt. 5:44). However, individuals in David's time who opposed the Lord's anointed king were opposing the Lord. The king was God's agent of judgment in Israel. This situation has no direct parallel in the church.
41:11-12 The psalmist regarded his continuing success over his enemies as a sign that God was happy with him. God had upheld him because he continued to do right. He was confident this situation would continue forever.
41:13 David concluded with a doxology. He was sure God would show mercy to those who were merciful. This consistency is in harmony with God's character, and it had proved true in David's personal experience.
This verse also appropriately concludes the first major section of the Book of Psalms (chs. 1-41).
