Isaiah 60:1-6: "1 Arise, shine, for your light has come, and the glory of the LORD has risen upon you. 2 For behold, darkness shall cover the earth, and thick darkness the peoples; but the LORD will arise upon you, and his glory will be seen upon you. 3 And nations shall come to your light, and kings to the brightness of your rising.
"4 Lift up your eyes all around, and see; they all gather together, they come to you; your sons shall come from afar, and your daughters shall be carried on the hip. 5 Then you shall see and be radiant; your heart shall thrill and exult, because the abundance of the sea shall be turned to you, the wealth of the nations shall come to you. 6 A multitude of camels shall cover you, the young camels of Midian and Ephah; all those from Sheba shall come. They shall bring gold and frankincense, and shall bring good news, the praises of the LORD."
Colossians 1:13: "He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son."
Isaiah 9:2: "The people who walked in darkness have seen a great light; those who dwelt in a land of deep darkness, on them has light shined."
Acts 26:17-18: "'... delivering you from your people and from the Gentiles - to whom I am sending you 18 to open their eyes, so that they may turn from darkness to light and from the power of Satan to God, that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.'"

Isaiah 60 is the main source for the hymn text; each of its first five verses corresponds to a hymn verse. The first verse of the hymn is from Isaiah 60:1 ("Arise and shine in splendor... The glory of the Lord is here"); the second verse of the hymn is from Isaiah 60:2 ("See earth in darkness lying... To you the Lord... has given / Great glory, honor, and delight"); and so on to verse five. I'd also like to point out that the parallelism in Isaiah 60:4 ("your sons shall come from afar, and your daughters shall be carried on the hip") is retained in the hymn: "Her sons come to Your glory; / Her daughters haste Your light to see."
The other three Biblical citations don't seem to appear as direct quotes in the hymn; rather, they just reiterate the various references to light and darkness throughout the hymn.
The last few lines of the hymn are "Your eyes will wake from slumber / As people without number / Rejoice to see the Morning Star." "The Morning Star" is a name for Jesus from Revelation 22:16.
