Psalm 21

From "ESV Gospel Transformation Bible" by ESV Bibles by Crossway:

       "As the full significance of this psalm is seen in light of Christ’s ministry fulfilling David’s plans, we understand that , having saved his people from their sins by Christ’s sacrifice, God raised him and granted him eternal life ( Ps. 21: 4 ; Rom. 4: 23– 25 ). As the risen victor over death, Christ earned authority to convey all the blessings he earned to his people whom he saves ( Ps. 21: 5– 8 ; Acts 13: 34 ). His “crown of fine gold” signifies his power to defeat all the enemies of his church ( Ps. 21: 3 , 9– 12 ; Rev. 14: 14 ). Because Christ submitted himself to God’s will through his sufficient sacrifice, God enforces his authority to bring all of his enemies into submission ( Ps. 21: 7 ; Heb. 10: 12– 13 ).

       Christ was then exalted to the right hand of his Father, and the “joy of [his] presence” was restored ( Ps. 21: 6 ; Heb. 1: 3 ). The joy of that reconciliation and the “power” of that co-regency explain the believer’s eternal song of “praise” ( Ps. 21: 13 ; Rev. 5: 9– 14 ). David trains believers to pray for more than just everyday nuisances. We must also pray “your kingdom come, your will be done” ( Matt. 6: 10 ), and this psalm assures us that these things will happen."
