Psalms 21:1

(Heb.: 21:2-3) The Psalm begins with thanksgiving for the bodily and spiritual blessings which Jahve has bestowed and still continues to bestow upon the king, in answer to his prayer. This occupies the three opening tetrastichs, of which these verses form the first. עז (whence עזּך, as in Psa 74:13, together with עזּך, Psa 63:3, and frequently) is the power that has been made manifest in the king, which has turned away his affliction; ישׁוּעה is the help from above which has freed him out of his distress. The יגיל, which follows the מה of the exclamation, is naturally shortened by the Kerמ into יגל (with the retreat of the tone); cf. on the contrary Pro 20:24, where מה is interrogative and, according to the sense, negative). The ἁπ. λεγ. ארשׁת has the signification eager desire, according to the connection, the lxx δέηεσιν, and the perhaps also cognate רוּשׁ, to be poor; the Arabic Arab. wrš, avidum esse, must be left out of consideration according to the laws of the interchange of consonants, whereas ירשׁ, Arab. wrṯ, capere, captare (cf. Arab. irṯ = wirṯ an inheritance), but not רוּשׁ (vid., Psa 34:11), belongs apparently to the same root. Observe the strong negation בּל: no, thou hast not denied, but done the very opposite. The fact of the music having to strike up here favours the supposition, that the occasion of the Psalm is the fulfilment of some public, well-known prayer.

David here speaks for himself in the first place, professing that his joy was in God's strength and in his salvation, and not in the strength or success of his armies. He also directs his subjects herein to rejoice with him, and to give God all the glory of the victories he had obtained; and all with an eye to Christ, of whose triumphs over the powers of darkness David's victories were but shadows. 1. They here congratulate the king on his joys and concur with him in them (Psa 21:1): "The king rejoices, he uses to rejoice in thy strength, and so do we; what pleases the king pleases us," Sa2 3:36. Happy the people the character of whose king it is that he makes God's strength his confidence and God's salvation his joy, that is pleased with all the advancements of God's kingdom and trusts God to bear him out in all he does for the service of it. Our Lord Jesus, in his great undertaking, relied upon help from heaven, and pleased himself with the prospect of that great salvation which he was thereby to work out. 2. They gave God all the praise of those things which were the matter of their king's rejoicing. (1.) That God had heard his prayers (Psa 21:2): Thou hast given him his heart's desire (and there is no prayer accepted but what is the heart's desire), the very thing they begged of God for him, Psa 20:4. Note, God's gracious returns of prayer do, in a special manner, require our humble returns of praise. When God gives to Christ the heathen for his inheritance, gives him to see his seed, and accepts his intercession for all believers, he give him his heart's desire. (2.) That God had surprised him with favours, and much outdone his expectations (Psa 21:3): Thou preventest him with the blessings of goodness. All our blessings are blessings of goodness, and are owing, no…

Ps 21 God’s people thank him for giving victory to the king.
