Psalms 21:1 - Clarke's commentary and critical notes on the Bible

To the chief Musician, A Psalm of David. The king shall joy in thy strength, O LORD; and in thy salvation how greatly shall he rejoice! The king shall joy - מלך משיחא melech Meshicha, "the King Messiah." - Targum. What a difference between ancient and modern heroes! The former acknowledged all to be of God, because they took care to have their quarrel rightly founded; the latter sing a Te Deum, pro forma, because they well know that their battle is not of the Lord. Their own vicious conduct sufficiently proves that they looked no higher than the arm of human strength. God suffers such for a time, but in the end he confounds and brings them to naught.
