Psalms 21:13

(Heb.: 21:14) After the song has spread abroad its wings in twice three tetrastichs, it closes by, as it were, soaring aloft and thus losing itself in a distich. It is a cry to God for victory in battle, on behalf of the king. "Be Thou exalted," i.e., manifest Thyself in Thy supernal (Psa 57:6, 12) and judicial (Psa 7:7.) sovereignty. What these closing words long to see realised is that Jahve should reveal for world-wide conquest this גּבוּרה, to which everything that opposes Him must yield, and it is for this they promise beforehand a joyous gratitude.

As the foregoing psalm was a prayer for the king that God would protect and prosper him, so this is a thanksgiving for the success God had blessed him with. Those whom we have prayed for we ought to give thanks for, and particularly for kings, in whose prosperity we share. They are here taught, I. To congratulate him on his victories, and the honour he had achieved (Psa 21:1-6). II. To confide in the power of God for the completing of the ruin of the enemies of his kingdom (Psa 21:7-13). In this there is an eye to Messiah the Prince, and the glory of his kingdom; for to him divers passages in this psalm are more applicable than to David himself. To the chief musician. A psalm of David.

21:13 Rise up (or be exalted, as in 57:5, 11; 108:5) expresses communal praise and joy in God’s greatness and power.
