From the Gospel of Luke we see the birth announcement of Jesus -

Suddenly, God's angel stood among them and God's glory blazed around them. They were terrified.

The angel said, "Don't be afraid. I'm here to announce a great and joyful event that is meant for everybody, worldwide: A Savior has just been born in David's town, a Savior who is Messiah and Master. This is what you're to look for: a baby wrapped in a blanket and lying in a manger."

At once the angel was joined by a huge angelic choir singing God's praises:

Glory to God in the heavenly heights,
Peace to all men and women on earth who please him.

Luke 2:9-14 (MSG)
