2. The passover was to be religiously observed at the time appointed, v. 21. Christ is our passover, that is sacrificed for us. We celebrate the memorial of that sacrifice and feast upon it, triumphing in our deliverance out of the Egyptian slavery of sin and our preservation from the sword of the destroying angel, the sword of divine justice, in the Lord's supper, which is our passover-feast, as the whole Christian life is, and must be, the feast of unleavened bread. It is here appointed that the prince shall prepare a sin-offering, to be offered for himself and the people, a bullock on the first day (v. 22) and a kid of the goats every other day (v. 23), to teach us, in all our attendance upon God for communion with him, to have an eye to the great sin-offering, by which transgression was finished and an everlasting righteousness brought in. On every day of the feast there was to be a burnt-offering, purely for the honour of God, of no less than seven bullocks and seven rams, with their meat-offering, which were wholly consumed upon the altar, and yet no waste, v. 23, 24.
