Joseph also went up from Galilee, from the city of Nazareth, to Judea, to the city of David which is called Bethlehem, because he was of the house and family of David, (Luke 2:4 NASB)
So David lived in the stronghold and called it the city of David. And David built all around from the Millo and inward. (2 Samuel 5:9 NASB)
One quirky thing I ran across here was the reference to the City of David. I stumbled on it because I have just finished studying 2 Samuel, and there the ‘City of David’ is Jerusalem. I checked, and the reference is in the Greek text of the Hebrew Scriptures which Luke would have used as well. I have a few commentaries for Luke, and there doesn’t seem to be a lot of ink used on this issue. But it’s definitely odd to me, and I believe it would have been somewhat odd for Luke’s audience as well.
