For the choirmaster. A Psalm of David. O LORD, the king rejoices in Your strength. How greatly he exults in Your salvation!
David could have given thanks to God in private, but he testified publicly that whatever blessings God conferred upon him redounded to the common good of all His people. Yet above all, the Holy Spirit directs our minds here to Christ, who was the end and perfection of this kingdom, teaching us we cannot be saved except under the Head God Himself appointed.

Commenting on Psalm 21:1-13
"The king shall joy in thy strength, O Lord." Jesus is a Royal Personage. The question, "Art thou a King then?" received a full answer from the Saviour's lips: "Thou sayest that I am a King. To this end was I born, and for this purpose came I into the world, that I might bear witness unto the truth." He is not merely a King...
David made God's strength his confidence and God's salvation his joy, not the success of armies. Happy the people whose king trusts God to bear him out in all he does for the service of His kingdom. Our Lord Jesus, in His great undertaking, relied upon help from heaven and pleased Himself with the prospect of that great salvation He was thereby to work out.
