Psalm 41:1-4

To the chief Musician, a Psalm of David. In this psalm is a prophecy concerning Christ, and concerning Judas Iscariot, as runs part of the title in the Syriac version; and in the Arabic version it is called a prophecy concerning the incarnation, and the salutation of Judas; and certain it is that Psalm 41:9 is to be understood of him, and of his betraying Christ into the hands of his enemies, since it is cited and applied to him by our Lord himself, John 13:18; so that having such a sure rule of interpretation, we may safely venture to explain the whole psalm of Christ, which treats both of his humiliation and exaltation; for it neither agrees with David wholly, nor with Hezekiah, to whom some ascribe it, as Theodoret remarks.
