Luke 2:5 YLT

³  and all were going to be enrolled, each to his proper city,

⁴  and Joseph also went up from Galilee, out of the city of Nazareth, to Judea, to the city of David, that is called Bethlehem, because of his being of the house and family of David,

⁵  to enroll himself with Mary his betrothed wife, being with child.

⁶  And it came to pass, in their being there, the days were fulfilled for her bringing forth,

⁷  and she brought forth her son -- the first-born, and wrapped him up, and laid him down in the manger, because there was not for them a place in the guest-chamber.
