Luke 2:4-6

New Revised Standard Version Catholic Edition

⁴ Joseph also went from the town of Nazareth in Galilee to Judea, to the city of David called Bethlehem, because he was descended from the house and family of David. ⁵ He went to be registered with Mary, to whom he was engaged and who was expecting a child. ⁶ While they were there, the time came for her to deliver her child.
