The king rejoices in your strength, Yahweh! How greatly he rejoices in your salvation!
2You have given him his heart's desire, and have not withheld the request of his lips. Selah.
3For you meet him with the blessings of goodness. You set a crown of fine gold on his head.
4He asked life of you, and you gave it to him, even length of days forever and ever.
5His glory is great in your salvation. You lay honor and majesty on him.
6For you make him most blessed forever. You make him glad with joy in your presence.
7For the king trusts in Yahweh. Through the loving kindness of the Most High, he shall not be shaken.
8Your hand will find out all of your enemies. Your right hand will find out those who hate you.
9You will make them as a fiery furnace in the time of your anger. Yahweh will swallow them up in his wrath. The fire will devour them.
10You will destroy their descendants from the earth, their posterity from among the children of men.
11For they intended evil against you. They plotted evil against you which cannot succeed.
12For you will make them turn their back, when you aim drawn bows at their face.
13Be exalted, Yahweh, in your strength. We will sing and praise your power.

Summary

Psalm 21 is the companion to Psalm 20 — the thanksgiving after battle, corresponding to the prayer before battle. The king reports that Yahweh answered every petition: he gave the king his heart's desire, blessed him with goodness, set a golden crown on his head, and granted him length of days. The theological anchor is verse 7: the king is not shaken because he trusts in Yahweh's loving kindness (hesed). The psalm closes with praise for Yahweh's exalted strength and a promise to sing of his power.

Themes

  • Gratitude as the answer to intercession — Psalm 20 prays, Psalm 21 thanks
  • The king's blessings as overflow of trust in Yahweh's hesed
  • Joy in God's presence as the highest form of blessing
  • The defeat of enemies as Yahweh's work, not the king's military skill
  • Exaltation of Yahweh as the conclusion of all victory praise

Key verses

  • Ps 21:1 — “The king rejoices in your strength, Yahweh! How greatly he rejoices in your salvation!”
  • Ps 21:6 — “You make him most blessed forever. You make him glad with joy in your presence.”
  • Ps 21:7 — “For the king trusts in Yahweh. Through the loving kindness of the Most High, he shall not be shaken.”

Context & background

Psalms 20 and 21 form a diptych — the pre-battle intercession and the post-battle thanksgiving — likely used together in the temple liturgy. The "length of days forever and ever" (v. 4) is remarkable: it goes beyond what any human king could experience, pointing forward to the Messianic king. The early church read Psalm 21 as prophetic of Christ's exaltation after resurrection — the crown, the length of days, the joy in God's presence all find their ultimate fulfillment in the risen and ascended Son. The Davidic king is always a type pointing beyond himself.

  • Psalm 20 — the paired pre-battle prayer that this psalm answers
  • Psalm 2:8-9 — the nations given to the anointed king — the same royal Messianic expectation
  • Revelation 19:12 — the rider on the white horse wears many crowns — v. 3's ultimate fulfillment
