Jesus was born in Bethlehem, Davids town.  This is the Star of David.  It reminds us of the song of Zechariah in Luke 1.

68 “Praise be to the Lord, the God of Israel,  because he has come to his people and redeemed them. 69 He has raised up a horn[c] of salvation for us in the house of his servant David 70 (as he said through his holy prophets of long ago), 71 salvation from our enemies and from the hand of all who hate us— 72 to show mercy to our ancestors and to remember his holy covenant, 73     the oath he swore to our father Abraham: 74 to rescue us from the hand of our enemies, and to enable us to serve him without fear 75     in holiness and righteousness before him all our days.”
