Then Moses called for all the elders of Israel
Not in age but in office, who were either heads of families, or at least principal men in the tribes; which explains in what manner he was to speak to the congregation of Israel, and convey to them the will of God concerning the observation of these feasts, ( Exodus 12:3 ) , and said unto them, draw out;
a lamb or a kid, out of the flocks on the tenth day of the month, and keep it up until the fourteenth, as in ( Exodus 12:3 Exodus 12:6 ) and take you a lamb, according to your families;
or "take ye of the flock" F18, whether a lamb or a kid; a lamb for every family, if there was a sufficient number in it to eat it up; if not, two or more families were to join and keep the feast together: and kill the passover;
the lamb for the passover, which was to be done on the fourteenth day of the month; and before the priesthood was established in the family of Aaron, and before the Israelites were possessed of the land of Canaan, and the temple was built at Jerusalem, the passover was killed by the heads of families, and in their own houses, but afterwards it was killed only by the priests, and at Jerusalem and in the temple there, see ( Deuteronomy 16:5 ) .
