13 Be exalted, Yahweh, in your strength, So we will sing and praise your power.
After these things I heard something like a loud voice of a great multitude in heaven, saying, "Hallelujah! Salvation, power, and glory belong to our God: for true and righteous are his judgments. For he has judged the great prostitute, who corrupted the earth with her sexual immorality, and he has avenged the blood of his servants at her hand." A second said, "Hallelujah! Her smoke goes up forever and ever." The twenty-four elders and the four living creatures fell down and worshiped God who sits on the throne, saying, "Amen! Hallelujah!" A voice came forth from the throne, saying, "Give praise to our God, all you his servants, you who fear him, the small and the great!" I heard something like the voice of a great multitude, and like the voice of many waters, and like the voice of mighty thunders, saying, "Hallelujah! For the Lord our God, the Almighty, reigns!
The righteous shall rejoice when he sees the vengeance. He shall wash his feet in the blood of the wicked; So that men shall say, "Most assuredly there is a reward for the righteous. Most assuredly there is a God who judges the earth."
They sang the song of Moses, the servant of God, and the song of the Lamb, saying, "Great and marvelous are your works, Lord God, the Almighty; Righteous and true are your ways, you King of the nations. Who wouldn't fear you, Lord, And glorify your name? For you only are holy. For all the nations will come and worship before you. For your righteous acts have been revealed."
I heard the angel of the waters saying, "You are righteous, who are and who were, you Holy One, because you have judged these things. For they poured out the blood of the saints and the prophets, and you have given them blood to drink. They deserve this." I heard the altar saying, "Yes, Lord God, the Almighty, true and righteous are your judgments."

Commentary on Psalms 21 Matthew Henry Commentary
Psalm 21
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,
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.
Psa 21:1-6
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.
In singing this we should rejoice in his joy and triumph in his exaltation.
Psa 21:7-13
The psalmist, having taught his people to look back with joy and praise on what God had done for him and them, here teaches them to look forward with faith, and hope, and prayer, upon what God would further do for them: The king rejoices in God (v. 1), and therefore we will be thankful; the king trusteth in God (v. 7), therefore will we be encouraged. The joy and confidence of Christ our King is the ground of all our joy and confidence.
