Numbers 28:16

16.And in the fourteenth day. It is true that the instruction here given has some connection with the feast of the passover, but since the sacrifices are avowedly treated of, and no mention is made of its other observances, except in this place, I have connected it with the continual sacrifice, as its concomitant or part. Moses cursorily refers, indeed, to what we have already seen, i.e., that the people should abstain from leaven for seven days, and eat unleavened bread; but he afterwards descends to the main point of which he here proposed to treat, viz., that the people should slay two bullocks as a burnt-offering, a ram, and seven lambs, together with a goat for a sin-offering; and that this sacrifice should be repeated through the whole week. In order, then, that the reverence paid to the passover should be increased, this extraordinary sacrifice was added to the continual one, partly that they might thus be more and more stimulated to devote themselves to God; partly that they might acknowledge how familiarly He had embraced them with His favor, inasmuch as He took these offerings from their flocks and herds, and required the sacred feast to be prepared for Him out of their cellars and granaries also; partly, too, that professing themselves to be worthy of eternal death, they should fly to Him to ask for pardon, and at the same time should understand that there was but one way of reconciliation, i.e., when God should be propitiated by sacrifice.
