Exodus 12:47BSB·traditional attribution

The whole congregation of Israel must celebrate it.

Matthew Henry Presbyterian @wholebiblehenry

Some further precepts are here given concerning the passover, as it should be observed in times to come. I. All the congregation of Israel must keep it, Exo 12:47. All that share in God's mercies should join in thankful praises for them. Though it was observed in families apart, yet it is looked upon as the act of the whole congregation; for the smaller communities constituted the greater.

And it came to pass the selfsame day,.... That the above ordinance was instituted and celebrated in the night: that the Lord did bring the children of Israel out of the land of Egypt, by their armies; by their several tribes, which were like so many armies, marching in large numbers, and with great order and regularity; see Gill on Exo 7:4.

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).
