He ordained Aaron by pouring some of the anointing oil on his head.

"The High Priest has had the anointing oil poured on his head and has been consecrated to wear the priestly garments, so he must not leave his hair uncombed or tear his clothes to show that he is in mourning.

(SEE 21:11)

Then take the anointing oil, pour it on his head, and anoint him.

Take some of the blood that is on the altar and some of the anointing oil, and sprinkle it on Aaron and his clothes and on his sons and their clothes. He, his sons, and their clothes will then be dedicated to me.

then as soon as the sin becomes known, the community shall bring a young bull as a sin offering. They shall bring it to the Tent of the LORD's presence;

He said to Aaron, "Take a young bull and a ram without any defects and offer them to the LORD, the bull for a sin offering and the ram for a burnt offering.

He shall offer a bull as a sacrifice to take away his own sins and those of his family.

When Aaron sacrifices the bull as the sin offering for himself and his family,

Those priests belonging to the tribe of Levi who are descended from Zadok are the only ones who are to come into my presence to serve me. I, the Sovereign LORD, command this. You will give them a young bull to offer as a sacrifice for sin.

and as the penalty for your sin you must bring to the LORD a female sheep or goat as an offering. The priest shall offer the sacrifice for your sin.

But burn the bull's flesh, its skin, and its intestines outside the camp. This is an offering to take away the sins of the priests.

Once a year Aaron is to perform the ritual for purifying the altar by putting on its four projections the blood of the animal sacrificed for sin. This is to be done every year for all time to come. This altar is to be completely holy, dedicated to me, the LORD."

Then they are to take a young bull and the required grain offering of flour mixed with olive oil; and you are to take another bull for the sin offering.

All those who had returned from exile then brought offerings to be burned as sacrifices to the God of Israel. They offered 12 bulls for all Israel, 96 rams, and 77 lambs; they also offered 12 goats to purify themselves from sin. All these animals were burned as sacrifices to the LORD.

What the Law could not do, because human nature was weak, God did. He condemned sin in human nature by sending his own Son, who came with a nature like our sinful nature, to do away with sin.

Christ was without sin, but for our sake God made him share our sin in order that in union with him we might share the righteousness of God.

And because he is himself weak, he must offer sacrifices not only for the sins of the people but also for his own sins.

He is not like other high priests; he does not need to offer sacrifices every day for his own sins first and then for the sins of the people. He offered one sacrifice, once and for all, when he offered himself.

The Law of Moses appoints men who are imperfect to be high priests; but God's promise made with the vow, which came later than the Law, appoints the Son, who has been made perfect forever.
