1 Chronicles 16:4-36: "4 Then he [David] appointed some of the Levites as ministers before the ark of the LORD, to invoke, to thank, and to praise the LORD, the God of Israel. 5 Asaph was the chief, and second to him were Zechariah, Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-edom, and Jeiel, who were to play harps and lyres; Asaph was to sound the cymbals, 6 and Benaiah and Jahaziel the priests were to blow trumpets regularly before the ark of the covenant of God. 7 Then on that day David first appointed that thanksgiving be sung to the LORD by Asaph and his brothers.
"8 Oh give thanks to the LORD; call upon his name; make known his deeds among the peoples! 9 Sing to him; sing praises to him; tell of all his wondrous works! 10 Glory in his holy name; let the hearts of those who seek the LORD rejoice! 11 Seek the LORD and his strength; seek his presence continually! 12 Remember the wondrous works that he has done, his miracles and the judgements he uttered, 13 O offspring of Israel his servant, sons of Jacob, his chosen ones!
"14 He is the LORD our God; his judgements are in all the earth. 15 Remember his covenant forever, the word that he commanded, for a thousand generations, 16 the covenant that he made with Abraham, his sworn promise to Isaac, 17 which he confirmed as a statute to Jacob, as an everlasting covenant to Israel, 18 saying, 'To you I will give the land of Canaan, as your portion for an inheritance.'
"19 When you were few in number, and of little account, and sojourners in it, 20 wandering from nation to nation, from one kingdom to another people, 21 he allowed no one to oppress them; he rebuked kings on their account, 22 saying, 'Touch not my anointed ones, do my prophets no harm!'
"23 Sing to the LORD, all the earth! Tell of his salvation from day to day. 24 Declare his glory among the nations, his marvelous works among all the peoples! 25 For great is the LORD, and greatly to be praised, and he is to be held in awe above all gods. 26 For all the gods of the peoples are idols, but the LORD made the heavens. 27 Splendor and majesty are before him; strength and joy are in his place. 28 Ascribe to the LORD, O clans of the peoples, ascribe to the LORD glory and strength! 29 Ascribe to the LORD the glory due his name; bring an offering and come before him! Worship the LORD in the splendor of holiness; 30 tremble before him, all the earth; yes, the world is established; it shall never be moved. 31 Let the heavens be glad, and let the earth rejoice, and let them say among the nations, 'The LORD reigns!' 32 Let the sea roar, and all that fills it; let the field exult, and everything in it! 33 Then shall the trees of the forest sing for joy before the LORD, for he comes to judge the earth. 34 Oh give thanks to the LORD, for he is good; for his steadfast love endures forever!
"35 Say also: 'Save us, O God of our salvation, and gather and deliver us from among the nations, that we may give thanks to your holy name, and glory in your praise. 36 Blessed be the LORD, the God of Israel, from everlasting to everlasting!' Then all the people said, 'Amen!' and praised the LORD."
2 Chronicles 5:13-14: "13 and it was the duty of the trumpeters and singers to make themselves heard in unison in praise and thanksgiving to the LORD), and when the song was raised, with trumpets and cymbals and other musical instruments, in praise to the LORD, 'For he is good, for his steadfast love endures forever,' the house, the house of the LORD, was filled with a cloud, 14 so that the priests could not stand to minister because of the cloud, for the glory of the LORD filled the house of God."
Colossians 3:16-17: "16 Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God. 17 And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him."
Mark 14:26: "And when they had sung a hymn, they went out to the Mount of Olives."

The first three citations (1 Chronicles 16:4-36, 2 Chronicles 5:13-14, and Colossians 3:16-17) seem to be the basis for the fifth verse: "Let ev'ry instrument be tuned for praise! / Let all rejoice who have a voice to raise! / And may God give us faith to sing always: / Alleluia!"
Mark 14:26 is referred to in the fourth verse: "And did not Jesus sing a psalm that night / When utmost evil strove against the light?"
