1 Chronicles 16:31-36: "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."
Psalm 126:3: "The LORD has done great things for us; we are glad."
Joel 2:26: "'You shall eat in plenty and be satisfied, and praise the name of the LORD your God, who has dealt wondrously with you. And my people shall never again be put to shame.'"
Psalm 95:6: "Oh come, let us worship and bow down; let us kneel before the LORD, our maker!"

The passage from 1 Chronicles 16 is the main source for the hymn. It appears most clearly in the hymn's third verse, which is drawn from verses 32-33 and likewise exhorts forest leaves, meadow grasses, and flowers to praise the Lord.
Psalm 126:3 appears at the end of the first verse: "My heart... Would then proclaim... what great things God has done for me."
Like parts of the passage from 1 Chronicles 16, the worship and praise in Joel 2:26 and Psalm 95:6 seem to appear rather generally throughout the hymn, of which the first two lines provide a good summary: "Oh, that I had a thousand voices / To praise my God with thousand tongues!"

Part of the fourth verse ("All creatures that have breath and motion... Help me to sing God's praises high") is drawn from Psalm 150:6: "Let everything that has breath praise the LORD! Praise the LORD!"
