Hark! The herald angels sing,
"Glory to the newborn King;
Peace on earth and mercy mild,
God and sinners reconciled!"
Joyful, all ye nations, rise,
Join the triumph of the skies;
With the angelic host proclaim,
"Christ is born in Bethlehem!"
Hark! The herald angels sing,
"Glory to the newborn King!"
Christ, by highest heav'n adored,
Christ, the everlasting Lord,
Late in time behold Him come,
Offspring of a virgin's womb.
Veiled in flesh the Godhead see,
Hail the incarnate Deity!
Pleased as Man with man to dwell,
Jesus, our Immanuel!
Hark! The herald angels sing,
"Glory to the newborn King!"
Hail, the heav'n-born Prince of Peace!
Hail, the Sun of Righteousness!
Light and life to all He brings,
Ris'n with healing in His wings.
Mild He lays His glory by,
Born that man no more may die,
Born to raise the sons of earth,
Born to give them second birth.
Hark! The herald angels sing,
"Glory to the newborn King!"

The text from Luke 2 is the main referent, although where Luke 2 has the angels "saying, 'Glory to God in the highest...,'" the hymn has them "sing, 'Glory to the newborn King.'"
The reconciliation mentioned in the Romans 5 text is in the first verse: "God and sinners reconciled!"
The line "Veiled in flesh the Godhead see" in the second verse comes from John 1:14. There doesn't seem to be a specific line in the hymn that comes from John 1:1, but that verse is often cited alongside John 1:14, so it's probably listed because of the second verse's description of the incarnation. Matthew 1:23 ("'Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel' (which means, God with us).") and possibly even Isaiah 7:14 (which Matthew 1:23 quotes) should also be cited since the name Immanuel is listed in the verse.
The third verse also contains an un-cited reference to Isaiah; the name "Prince of Peace" is from Isaiah 9:6. "The Sun of Righteousness" and "Ris'n with healing in His wings" come from (the un-cited) Malachi 4:2: "But for you who fear my name, the sun of righteousness shall rise with healing in its wings. You shall go out leaping like calves from the stall."
Finally, John 11:26 seems to be present in "Born that man no more may die."
