The psalm is arranged into five sections: two small sections at the beginning and end, and three larger sections in the middle. The first section (v. 1-4) introduces the twin themes: God’s character and his covenant with David. In this psalm, his character is defined by his steadfast love and his faithfulness. Both of these words are applied in terms of his covenant with David–the promise that the seed of David will sit on an everlasting throne (v. 3-4). And this is crucial: the psalmist says he will sing of God’s steadfast love and faithfulness forever.
