And of the blood which was upon the altar. — That is, some of the blood of the ram of consecration, which was probably kept in the bowl, and placed upon the altar for this purpose. Whether the anointing oil and the blood were sprinkled separately, or whether they were mixed together, cannot possibly be gathered either from this passage, or from Exodus 29:21, which gives the order. As the sacred garments were the badge of office, they received the same cleansing and sanctification as the priests themselves. Hence the remark of the apostle, “almost all things were by the law purged with blood” (Hebrews 9:22).
