You are not to eat anything leavened; eat unleavened bread in all your homes.”
Moses and Aaron here receive of the Lord what they were afterwards to deliver to the people concerning the ordinance of the passover, to which is prefixed an order for a new style to be observed in their months (Exo 12:1, Exo 12:2): This shall be to you the beginning of months.
Commenting on Exodus 12:1-20
Ye shall eat nothing leavened,.... Bread or anything else that had any leaven in it: in all your habitations shall ye eat unleavened bread, that is, if they eat any bread at all, it must be such; otherwise they might eat cakes of almonds or of eggs mixed with sugar, provided there was no leaven used, and this the Jews call the rich unleavened bread...
UNLEAVENED BREAD. (Exo. 12:15-51) Seven days shall ye eat unleavened bread, &c.--This was to commemorate another circumstance in the departure of the Israelites, who were urged to leave so hurriedly that their dough was unleavened (Exo 12:39), and they had to eat unleavened cakes (Deu 16:3).
