Luke 2:5
Ver. 5. To be taxed with Mary his espoused wife,.... Whom also he had married, though he had not known her in a carnal way; she came along with him to be taxed and enrolled also, because she was of the same family of David, and belonged to the same city:
being great with child; very near her time, and yet, though in such circumstances, was obliged by this edict, to come to Bethlehem; and the providence in it was, that she might give birth there, and so the prophecy in Mic 5:2 have its accomplishment: this was an instance, and an example, of obedience to civil magistrates.
