Then Moses summoned all the elders of Israel and told them, “Go at once and select for yourselves a lamb for each family, and slaughter the Passover lamb.
Some rules here are temporary, given for that one night; others are perpetual law. The Passover itself means God's passing over, when His wrath like a deluge covered Egypt but left Israel untouched. I shall touch this lightly now, since the fuller exposition belongs where we treat the Law itself.
AI summary
Moses faithfully taught the elders all God had commanded him. The people must not stir out of doors that night, staying under the protection of the blood; their safety hangs on the sprinkled mark, not on their own wisdom or strength. Later they must teach their children what this service means.

Commenting on Exodus 12:21-28
Moses called the elders, who were heads of families and principal men in the tribes, to convey God's will. Each family was to take a lamb and keep it until the fourteenth day, then kill it. Before Aaron's priesthood and before the temple, the heads of families killed the lamb in their own houses.
