Psalm 138
This psalm was perhaps composed by David when he was newly advanced to his throne, 2 Sam. 5, 1 Chron. 12. In it, (1.) He looks back with thankfulness upon the experience he had of God's goodness to him, ver. 1-3. (2.) He looks forward with comfort, in hopes that others would go on like him to praise God, ver. 4-5; and that God would continue to do good to him, ver. 6-8.
While I sing these lofty lines, let the sense of the unnumbered mercies I have received from God, and the hopes of his everlasting loving-kindness, tune and animate my heart.
