Draw out - i. e. draw the lamb from the fold and then take it to the house.

The passover - The word is here applied to the lamb; an important fact, marking the lamb as the sign and pledge of the exemption of the Israelites.

Kill the passover - That is, the lamb, which was called the paschal or passover lamb. The animal that was to be sacrificed on this occasion got the name of the institution itself: thus the word covenant is often put for the sacrifice offered in making the covenant; so the rock was Christ, 1 Corinthians 10:4; bread and wine the body and blood of Christ, Mark 14:22, Mark 14:24. St. Paul copies the expression, 1 Corinthians 5:7 : Christ our passover (that is, our paschal lamb) is sacrificed for us.

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.

and take you a lamb, according to your families; or "take ye of the flock" (r), 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.

(r) "de filiis gregis", Onk. & Jon.

Of the directions given by Moses to the elders of the nation, the leading points only are mentioned here, viz., the slaying of the lamb and the application of the blood (Exodus 12:21, Exodus 12:22). The reason for this is then explained in Exodus 12:23, and the rule laid down in Exodus 12:24-27 for its observance in the future.

Exodus 12:21-22

"Withdraw and take:" משׁך is intransitive here, to draw away, withdraw, as in Judges 4:6; Judges 5:14; Judges 20:37. אזוב אגדּת: a bunch or bundle of hyssop: according to Maimonides, "quantum quis comprehendit manu sua." אזוב (ὕσσωπος) was probably not the plant which we call hyssop, the hyssopus officinalis, for it is uncertain whether this is to be found in Syria and Arabia, but a species of origanum resembling hyssop, the Arabian zter, either wild marjoram or a kind of thyme, Thymus serpyllum, mentioned in Forsk. flora Aeg. p. 107, which is very common in Syria and Arabia, and is called zter, or zatureya, the pepper or bean plant. "That is in the bason;" viz the bason in which the blood had been caught when the animal was killed. והגּעתּם, "and let it reach to, i.e., strike, the lintel:" in ordinary purifications the blood was sprinkled with the bunch of hyssop (Leviticus 14:51; Numbers 19:18). The reason for the command not to go out of the door of the house was, that in this night of judgment there would be no safety anywhere except behind the blood-stained door.

Then Moses called for all the elders of Israel, and said unto them, Draw out and take you a lamb according to your families, and kill the passover.

lamb: or, kid

21-25. Then Moses called for all the elders of Israel, &c.-Here are given special directions for the observance.

12:21-28 That night, when the first-born were to be destroyed, no Israelite must stir out of doors till called to march out of Egypt. Their safety was owing to the blood of sprinkling. If they put themselves from under the protection of that, it was at their peril. They must stay within, to wait for the salvation of the Lord; it is good to do so. In after-times they should carefully teach their children the meaning of this service. It is good for children to ask about the things of God; they that ask for the way will find it. The keeping of this solemnity every year was, 1. To look backward, that they might remember what great things God had done for them and their fathers. Old mercies, to ourselves, or to our fathers, must not be forgotten, that God may be praised, and our faith in him encouraged. 2. It was designed to look forward, as an earnest of the great sacrifice of the Lamb of God in the fulness of time. Christ our passover was sacrificed for us; his death was our life.
