Now it happened in those days, that a decree went out from Caesar Augustus that all the world should be enrolled.
It is probable that the reason why this enrolment, or census, is said to have been throughout the whole Jewish nation, was to distinguish it from that partial one, made ten years after, mentioned Acts 5:37, which does not appear to have extended beyond the estates of Archelaus, and which gave birth to the insurrection excited by Judas of Galilee. See Josephus, Ant. book xx. c. 3.
