2. Mose 12:13

The blood shall be to you for a token - It shall be the sign to the destroying angel, that the house on which he sees this blood sprinkled is under the protection of God, and that no person in it is to be injured. See Clarke on Exo 12:11 (note).

THE PASSOVER INSTITUTED. (Exo 12:1-10) the Lord spake unto Moses--rather, "had spoken unto Moses and Aaron"; for it is evident that the communication here described must have been made to them on or before the tenth of the month.

And the blood shall be to you for a token upon the houses where you are,.... The blood of the passover lamb being sprinkled on the two sideposts and upper doorposts of the houses inhabited by the Israelites, or where they were eating the passover; this should be a sign or token to them of the Lord's making good his promises, to them, and so of their safety, and to the destroying angel not to enter therein, but pass by and save them: and when I see the blood, I will pass over you; for which reason this ordinance now instituted was called the passover, because the Lord, on sight of the blood sprinkled, passed over the houses of the Israelites to those of the Egyptians; or "leaped", as Jarchi says, the word signifies, skipped from one Egyptian house to another, passing by that of the Israelites: and the plague shall not be upon you, to destroy you, when I smite the land of Egypt, the pestilence with which the firstborn should be destroyed.

This chapter gives an account of one of the most memorable ordinances, and one of the most memorable providences, of all that are recorded in the Old Testament. I. Not one of all the ordinances of the Jewish church was more eminent than that of the passover, nor is any one more frequently mentioned in the New Testament; and we have here an account of the institution to it. The ordinance consisted of three parts: - 1. The killing and eating of the paschal lamb (Exo 12:1-6, Exo 12:8-11). 2. The sprinkling of the blood upon the door-posts, spoken of as a distinct thing (Heb 11:28), and peculiar to this first passover (Exo 12:7), with the reason for it (Exo 12:13). 3. The feast of unleavened bread for seven days following; this points rather at what was to be done afterwards, in the observance of this ordinance (Exo 12:14-20). This institution is communicated to the people, and they are instructed in the observance, (1.) Of this first passover (Exo 12:21-23). (2.) Of the after passovers (Exo 12:24-27). And the Israelites' obedience to these orders (Exo 12:28). II. Not one of all the providences of God concerning the Jewish church was more illustrious, or is more frequently mentioned, than the deliverance of the children of Israel out of Egypt. 1. The firstborn of the Egyptians are slain (Exo 12:29, Exo 12:30). 2. Orders are given immediately for their discharge (Exo 12:31-33). 3. They begin their march. (1.) Loaded with their own effects (Exo 12:34). (2.) Enriched with the spoils of Egypt (Exo 12:35, Exo 12:36). (3.) Attended with a mixed multitude (Exo 12:37, Exo 12:38). (4.) Put to their shifts for present supply (Exo 12:39). The event is dated (Exo 12:40-42). Lastly, A recapitulation in the close, [1.] Of this memorable ordinance, with some additions (Exo 12:43-49).
