What does Psalm 41:13 mean?

Psalm 41 begins and ends with references to blessing. David's initial statement was about God's response to someone who acts with love and compassion for the disadvantaged (Psalm 41:1–3). In this psalm, David connected that healing to forgiveness of sin, including his own, and his confidence that God would not allow enemies to overwhelm David's life. The psalm includes David's petition to the Lord and ends with his praise of the Lord.

While spoken of as a single book, the Psalms are often divided into five segments, also called "books." This verse concludes Book One of Psalms with a doxology; the other four books of Psalms also end in doxologies (72:18–20; 89:52; 106:48; 150:1–6). David's praise of the Lord shows his trust in God to restore his health, defeat his enemies, and return him to his rightful rule over Israel.

This verse also refers to the God of Israel as eternal, "from everlasting to everlasting." He has no beginning and no end. David, like all human beings, was finite (Psalm 39:4–6), but he wisely entrusted his life to the eternal God.
