1. And it came to pass on the eighth day We have here related how Aaron and his sons, after the time of their consecration was fulfilled, began to execute their office. It was necessary that He should be his brother’s disciple, in order to follow the pattern laid down by God. And we must bear in mind that Moses, who was not appointed priest by a solemn rite, sanctified the others, in order that the authority and the efficacy of the outward sign should rest in God alone. This, therefore, is contained in the earlier portion of the chapter, how, after Aaron had been initiated in the priest’s office for seven days, He commenced the work entrusted to him by God’s command: the second part shews how the sacrifices were approved by a divine miracle, in ratification of the priesthood which God had instituted. But, first of all, He enumerates the ordinary kinds of sacrifice, viz., for sin, the burnt-offering; and for thanksgiving, the sacrifice with the meat-offering (minha) and the sprinkling: that in every respect Aaron might be accounted the lawful priest of God.
