Psalm 72:5-11: "5 May they fear you while the sun endures, and as long as the moon, throughout all generations! 6 May he be like rain that falls on the mown grass, like showers that water the earth! 7 In his days may the righteous flourish, and peace abound, till the moon be no more!
"8 May he have dominion from sea to sea, and from the River to the ends of the earth! 9 May desert tribes bow down before him, and his enemies lick the dust! 10 May the kings of Tarshish and of the coastlands render him tribute; may the kings of Sheba and Seba bring gifts! 11 May all kings fall down before him, all nations serve him!"
Psalm 72:17: "May his name endure forever, his fame continue as long as the sun! May people be blessed in him, all nations call him blessed!"
Revelation 11:15: "Then the seventh angel blew his trumpet, and there were loud voices in heaven, saying, 'The kingdom of the world has become the kingdom of our Lord and of his Christ, and he shall reign forever and ever.'"
Psalm 8:2: "Out of the mouth of babies and infants, you have established strength because of your foes, to still the enemy and the avenger."
Matthew 21:15-16: "15 But when the chief priests and the scribes saw the wonderful things that he did, and the children crying out in the temple, 'Hosanna to the Son of David!' they were indignant, 16 and they said to him, 'Do you hear what these are saying?' And Jesus said to them, 'Yes; have you never read, "Out of the mouth of infants and nursing babies you have prepared praise"?'"
Matthew 11:28: "'Come to me, all who labor and are heavy laden, and I will give you rest.'"

1 Jesus shall reign where'er the sunDoes its successive journeys run;His kingdom stretch from shore to shoreTill moons shall wax and wane no more.2 To Him shall endless prayer be made,And endless praises crown His head;His name like sweet perfume shall riseWith ev'ry morning sacrifice.3 People and realms of ev'ry tongueDwell on His love with sweetest song;And infant voices shall proclaimTheir early blessings on His name.4 Blessings abound where'er He reigns:The pris'ners leap, unloose their chains,The weary find eternal rest,And all who suffer want are blest.5 Let ev'ry creature rise and bringHonors peculiar to our King;Angels descend with songs again,And earth repeat the loud amen.

The two passages from Psalm 72 and Revelation 11:15 are the basis for the first verse.
Psalm 8:2 and Matthew 21:15-16 appear at the end of the third verse: "And infant voices shall proclaim / Their early blessings on His name."
Matthew 11:28 is alluded to in the fourth verse: "The weary find eternal rest."
+++
The lines "Blessings abound where'er He reigns: / The pris'ners leap, unloose their chains" at the beginning of the fourth verse may refer to part of Isaiah 61:1: "The Spirit of the Lord GOD is upon me, because the LORD has anointed me... to proclaim liberty to the captives, and the opening of the prison to those who are bound...." Jesus quotes this passage in Luke 4:18.
