Luke 2:4-6

Revised Standard Version Catholic Edition

⁴ And 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 lineage of David, ⁵ to be enrolled with Mary, his betrothed, who was with child. ⁶ And while they were there, the time came for her to be delivered.
