Exodus 29:20

Thou shalt kill the ram—take of his blood, and put it upon the tip, &c.— This extraordinary ceremony is enjoined (Leviticus 14:14.) in the curing of the leper; and from thence, as well as from the sprinkling of the blood and the oil upon the priests and their garments, Exodus 29:21 that they might be hollowed, one would be apt to conclude, that the total, entire purification and sanctification of their persons, from head to foot, was implied: or, in other words, that they were hereby taught, as being now sanctified and set apart to the Lord, that they should dedicate all their faculties and powers to his service; their ear to the hearing and study of the law; their hands to diligence in the sacred ministry, and their feet to walking in the way of God's precepts. See Jeremiah 6:10. Ecclesiastes 9 l0. Proverbs 1:15. The blood upon the altar, and the anointing oil, Exodus 29:21 were to be sprinkled upon their garments, to represent the purification of our souls by the virtues of the blood of Christ and the efficacy of the Divine Spirit.
