Introduction to Psalm 21

To the chief Musician, a Psalm of David. This psalm was either written by David; and therefore called a "psalm of David"; or it was written, as it may be rendered, "for David", by some other person, on account of his victories and triumphs; or rather "concerning David" {s}; that is, concerning the Messiah, the son of David, as Kimchi says some expound it; or concerning the Messiah, who is called David,

Ezekiel 37:24; and Jarchi observes, that their Rabbins interpret it of the Messiah; but, says he, it is right to explain it, moreover, of David himself, for an answer to the heretics (Christians) who err in it; and various passages in this psalm are by the Jewish writers understood of the Messiah; as "the King", in Psalms 20:1 is in the Targum called the King Messiah; Psalms 21:4 is in the Talmud applied {t} to him; Psalms 21:3 are in Zohar {u}, and in the Midrashes {w}, interpreted of him; and many Christian writers understand the whole of him; which is right: though Theodoret thinks it was penned on the account of the health of King Hezekiah, and his restoration from his disease; which is not likely.
