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,
