What does Psalm chapter 108 mean?
This psalm is unique in that it is directly copied from the text of two others (Psalm 57; 60). David wrote both originals—so even if he did not personally arrange Psalm 108, it is properly called "of David." The original psalms dealt with dangers and struggles, which led to resolve and the intent to maintain faith. The ending parts of those psalms, expressing confidence and expectation, are combined here in Psalm 108.The psalm opens with a nearly word-for-word duplication of Psalm 57:7–11. David declares his unwavering loyalty and trust in the Lord. He intends to praise God with music from the very earliest part of the day. David also intends to see the Lord's praise spread among all the people of the world (Psalm 108:1–5).
The second half of the psalm is copied from Psalm 60:5–12. This expresses God's ultimate power and sovereignty. The original psalm was written when Israel was facing a war to the north and a surprise attack from the south (Psalm 60:1–5). Despite fears and doubts, David found reassurance. The Lord noted His power over the regions of Israel, as well as His intent to conquer the nation's enemies. Despite it seeming—for now—that God is not helping their armies, David trusts that the Lord will bring victory, eventually (Psalm 108:6–13).
