Luke 2:10-14: "10 And the angel said to them, 'Fear not, for behold, I bring you good news of great joy that will be for all the people. 11 For unto you is born this day in the city of David a Savior, who is Christ the Lord. 12 And this will be a sign for you: you will find a baby wrapped in swaddling cloths and lying in a manger.' 13 And suddenly there was with the angels a multitude of the heavenly host praising God and saying, 14 'Glory to God in the highest, and on earth peace among those with whom he is pleased!'"
Luke 2:20: "And the shepherds returned, glorifying and praising God for all they had heard and seen, as it had been told them."

On Christmas night all Christians sing
To hear the news the angels bring,
On Christmas night all Christians sing
To hear the news the angels bring,
News of great joy, news of great mirth,
News of our merciful King's birth.
Then why should men on earth be so sad,
Since our Redeemer made us glad,
Then why should men on earth be so sad,
Since our Redeemer made us glad,
When from our sin He set us free,
All for to gain our liberty?
When sin departs before His grace,
Then life and health come in its place,
When sin departs before His grace,
Then life and health come in its place;
Angels and men with joy may sing,
All for to see the newborn King.
All out of darkness we have light,
Which made the angels sing this night,
All out of darkness we have light,
Which made the angels sing this night:
"Glory to God and peace to men
Now and forevermore. Amen."

Because there are only two Biblical citations, there's not much to say about this one. The hymn comes primarily from Luke 2, although - as I've pointed out before with other Christmas hymns - this hymn has the angels "sing[ing]," where in the text, they merely speak.
The last verse's mentioning light could have any of a number of Biblical sources. Jesus is referred to as a "light" multiple times (even calling Himself "the light of the world" in John 8:12). Because this is a Christmas hymn (and because the only cited Biblical texts are from Luke), I'd suggest Luke 1:77-79, where Zechariah prophesies that John will prepare the way of the Lord "77 'to give knowledge of salvation to his people in the forgiveness of their sins, 78 because of the tender mercy of our God, whereby the sunrise shall visit us from on high 79 to give light to those who sit in darkness and in the shadow of death, to guide our feet into the way of peace.'"
