David not only penned it, but sang it himself in a devout religious manner unto the Lord, concerning the words or affairs of Cush the Benjamite, that is, of Saul himself, whose barbarous usage of David bespoke him rather a Cushite, or Ethiopian, than a true-born Israelite.

David, thus basely abused, has recourse to the Lord. The injuries men do us should drive us to God, for to him we may commit our cause. Nay, he sings to the Lord; his spirit was not ruffled by it, nor cast down, but so composed and cheerful that he was still in tune for sacred songs and it did not occasion one jarring string in his harp.
