Psalm 20 prayed for the king before battle. This psalm answers it — the same voice, now celebrating a victory already won, crediting every part of it to the God who was asked for help in the first place.

The King Shall Joy In Thy Strength, O LORD
“The king shall joy in thy strength, O LORD; and in thy salvation how greatly shall he rejoice! Thou hast given him his heart’s desire, and hast not withholden the request of his lips.”
Psalm 21:1-2
“Thy strength,” not his own, opens the psalm — the king’s joy is explicitly located in a power that belongs to someone else. Every request named in Psalm 20 is here reported as granted in full, nothing withheld.
“For thou preventest him with the blessings of goodness: thou settest a crown of pure gold on his head.”
Psalm 21:3
“Preventest” carries its older meaning here — to come before, to arrive ahead of. God’s blessing reaches the king before he even finishes asking for it, and the crown itself is credited to God’s own hand rather than to any human coronation.
He Asked Life Of Thee
“He asked life of thee, and thou gavest it him, even length of days for ever and ever. His glory is great in thy salvation: honour and majesty hast thou laid upon him.”
Psalm 21:4-5
A request simply for survival in battle is answered with something far larger — “length of days for ever and ever” reaches well past any single king’s natural lifespan, language later readers would recognize pointing toward the everlasting reign eventually promised to David’s greater descendant.
The King Trusteth In The LORD
“For the king trusteth in the LORD, and through the mercy of the most High he shall not be moved. Thine hand shall find out all thine enemies: thy right hand shall find out those that hate thee.”
Psalm 21:7-8
Verse 7 is the psalm’s hinge — everything before it describes what God has already given; everything after it describes what God will still do to those who oppose His anointed. The king’s security rests entirely on the single word “trusteth.”
Be Thou Exalted, LORD, In Thine Own Strength
“For they intended evil against thee: they imagined a mischievous device, which they are not able to perform… Be thou exalted, LORD, in thine own strength: so will we sing and praise thy power.”
Psalm 21:11, 13
The psalm’s final line quietly redirects everything one more time — even a psalm celebrating the king’s own crown, glory, and victory closes by asking for God alone to be exalted. Whatever honor the king received in the opening verses, the last word belongs entirely to the LORD.
