What does Psalm 108:5 mean?

When David originally wrote these words (Psalm 57:11), they were about his commitment to faith in God despite great personal danger (Psalm 57:1–4; 1 Samuel 19:1–2). David knew that the Lord was supreme and everything which happened would be under His control (1 Thessalonians 5:9–11). This reflected David's understanding of God's sovereignty: His absolute power and authority over all of creation. Here, David both recognizes and yearns for God's majestic Lordship.

Scripture presents the Lord as consistently loving and caring (Psalm 108:4; Jeremiah 31:3). Yet He is also the Creator (Genesis 1:1; John 1:3). Everything which He created is for His own glory. To the extent human beings experience glory, it is only by reflecting that which comes from God Himself. The glory of the Lord is a dominant theme in the entire Bible (Psalm 29:1–2; Deuteronomy 5:24; Luke 2:9; John 1:14; Colossians 3:4).

The first five verses of this psalm are taken nearly word-for-word from David's Psalm 57:7–11. The last eight repeat his words from Psalm 60:5–12.
