Luke 2:6

6 And so it was, that, while they were there, the days were accomplished that she should be delivered.

Ver. 6. The days were accomplished ] Her delivery might well be hastened, or at least facilitated, by her long journey; for it was no less than four days’ journey from Nazareth to Bethlehem. Some say she was gravida, but not gravata; great-bellied, but not unwieldy: Lumen enim quod in se habebat, pondus habere non poterat, saith Augustine; but I am not bound to believe him.
