INTRODUCTION TO PSALM 14 To the chief Musician, a Psalm of David. The argument of this psalm, according to Theodoret, is Sennacherib's invasion of Judea, when he sent Rabshakeh to Hezekiah, with menaces and curses; upon which Hezekiah implored divine help, and obtained it, and the Assyrian army was destroyed by an angel; of all which he thinks this psalm was prophetic.
