Leviticus 16:11 - Exposition

After having offered the bullock for his own sin offering, and presented the two goats, which constituted the sin offering of the people, and offered one of them, Aaron kills the bullock for the sin offering. A considerable interval had to elapse before he could make use of the bullock's blood for purposes of propitiation, and during this interval, occupied by his entrance into the holy of holies with the incense, the blood was held by an attendant, probably by one of his sons, and prevented from coagulating by being kept in motion.
