It is confessed that David was a type of Christ, and that many passages of the Psalms, though literally understood of David, yet had a further and mystical reference to Christ. But there are some other passages, which were directly, and immediately intended for, and are properly to be understood of the Messiah; though withal there may be some respect and allusion to the state of the penman himself. And this seems to be the state of this psalm, which is understood of the Messiah, by the Hebrew doctors themselves, and by Christ himself and by his apostles. And there are many passages in it, which were literally accomplished in him, and cannot be understood of any other. In this psalm David speaks of the humiliation of Christ, ver. 1-21. Of the exaltation of Christ, ver. 22-31. To the chief musician upon Aijeleth Shahar, A psalm of David. Title of the psalm.
