 As the divine act of Israel's redemption was of eternal significance, so the commemoration of that act was to be an eternal ordinance, and to be upheld as long as Israel should exist as the redeemed people of the Lord, i.e., to all eternity, just as the new life of the redeemed was to endure for ever. For the Passover, the remembrance of which was to be revived by the constant repetition of the feast, was the celebration of their birth into the new life of fellowship with the Lord. The preservation from the stroke of the destroyer, from which the feast received its name, was the commencement of their redemption from the bondage of Egypt, and their elevation into the nation of Jehovah. The blood of the paschal lamb was atoning blood; for the Passover was a sacrifice, which combined in itself the signification of the future sin-offerings and peace-offerings; in other words, which shadowed forth both expiation and quickening fellowship with God. The smearing of the houses of the Israelites with the atoning blood of the sacrifice set forth the reconciliation of Israel and its God, through the forgiveness and expiation of its sins; and in the sacrificial meal which followed, their communion with the Lord, i.e., their adoption as children of God, was typically completed. In the meal the sacrificium became a sacramentum, the flesh of the sacrifice a means of grace, by which the Lord adopted His spared and redeemed people into the fellowship of His house, and gave them food for the refreshing of their souls.

verses 15-20
Judging from the words “I brought out” in Exo 12:17, Moses did not receive instructions respecting the seven days' feast of Mazzoth till after the Exodus from Egypt; but on account of its internal and substantial connection with the Passover, it is placed here in immediate association with the institution of the paschal meal. “Seven days shall he eat unleavened bread, only (אך) on the first day (i.e., not later than the first day) he shall cause to cease (i.e., put away) leaven out of your houses.” The first day was the 15th of the month (cf. Lev 23:6; Num 28:17). On the other hand, when בּראשׁון is thus defined in Exo 12:18, “on the 14th day of the month at even,” this may be accounted for from the close connection between the feast of Mazzoth and the feast of Passover, inasmuch as unleavened bread was to be eaten with the paschal lamb, so that the leaven had to be cleared away before this meal.
