God’s blessing on his army. Psalm 21 is an assurance of God’s blessing on the king. Both psalms, as is the case with all the royal psalms, speak ultimately of the great King to come, the Lord Jesus. Psalm 21 has four movements: (1) a declaration of praise to God by the king (vv. 1, 2); (2) a review of God’s blessing on the king (vv. 3–7); (3) an expectation of the final destruction of all enemies of the king (vv. 8–12); (4) a renewed commitment by the people to praise God (v. 13).
