And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.
Ye shall observe ... The seven days of this feast were to commence the day after the Passover. It was a distinct festival following that feast; but although this feast was instituted, like the Passover, before the departure, the observance of it did not take place until after.
For in this self-same day have I brought your armies out of the land of Egypt, [Septuagint, exaxoo teen dunamin humoon] - will I lead out your hosts.
