Isaiah 9:6: "For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace."
Luke 1:67-75: "And his father Zechariah we filled with the Holy Spirit and prophesied, saying, 'Blessed be the Lord God of Israel, for he has visited and redeemed his people and has raised up a horn of salvation for us in the house of his servant David, as he spoke by the mouth of his holy prophets from of old, that we should be saved from our enemies and from the hand of all who hate us; to show the mercy promised to our fathers and to remember his holy covenant, the oath that he swore to our father Abraham, to grant us that we, being delivered from the hand of our enemies, might serve him without fear, in holiness and righteousness before him all our days.'"
Isaiah 61:1-2: "The Spirit of the Lord GOD is upon me, because the LORD has anointed me to bring good news to the poor; he has sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to those who are bound; to proclaim the year of the LORD's favor, and the day of vengeance of our God; to comfort all who mourn."
2 Peter 1:3-4: "His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence, by which he has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire."

Come, Thou long-expected Jesus,
Born to set Thy people free;
From our fears and sins release us;
Let us find our rest in Thee.
Israel's strength and consolation,
Hope of all the earth Thou art,
Dear desire of ev'ry nation,
Joy of ev'ry longing heart.
Born Thy people to deliver;
Born a child and yet a king!
Born to reign in us forever,
Now Thy gracious kingdom bring.
By Thine own eternal Spirit
Rule in all our hearts alone;
By Thine all-sufficient merit
Raise us to Thy glorious throne.

"Born to set Thy people free" in the first verse seems to come from Zechariah's "a horn of salvation for us" in the Luke text, although both selections from Isaiah hint at the same thing.
The rest of the first stanza (starting from "From our fears and sins release us") is clearly from the Isaiah 61 text.
"Born Thy people to deliver" returns to the Luke text, specifically "the Lord God of Israel... has visited and redeemed his people... that we should be saved from our enemies and from the hand of all who hate us," although it also connects to the "proclaim[ing] liberty to the captives, and the opening of the prison to those who are bound" in Isaiah 61.
"Born a child and yet a king" seems to reference the Isaiah 9 text. In word choice, it matches "For to us a child is born," and while a king isn't listed in that verse, "Prince of Peace" is pretty close and has the same idea.
The 2 Peter text also seems to contribute to the lines "Born to set Thy people free; / From our fears and sins release us," but I think most of its influence is in the second half of the second stanza. "Raise us to Thy glorious throne" seems comparable with "escap[ing] from the corruption that is in the world because of sinful desire" in order to "become partakers of the divine nature."
