Exodus 29:19 - Joseph Benson’s Commentary on the Old and New Testaments

There must be a peace-offering; it is called the ram of consecration, because there was more in this, peculiar to the occasion, than in the other two. In the burnt-offering, God had the glory of their priesthood, in this they had the comfort of it. And in token of a mutual covenant between God and them, the blood of this sacrifice was divided between God and them, part of the blood was sprinkled upon the altar round about, and part upon them, upon their bodies, and upon their garments. Thus the benefit of the expiation made by the sacrifice was applied and assured to them, and their whole selves, from head to foot, sanctified to the service of God. The blood was put upon the extreme parts of the body, to signify that it was all, as it were, enclosed and taken in for God, the tip of the ear and the great toe not excepted. And the blood and oil signified the blood of Christ, and the graces of the Spirit, which constitute and complete the beauty of holiness, and recommend us to God. The flesh of the sacrifice, with the meat-offering annexed to it, was likewise divided between God and them, that (to speak with reverence) God and they might feast together, in token of friendship and fellowship.
