“Then Aaron will offer the bull as a sin offering for himself. He will purify himself and his family. He will kill the bull for the sin offering for himself.
But only the high priest could go into the second room, and he went in only once a year. Also, he could never enter that room without taking blood with him. He offered that blood to God for himself and for the sins the people committed without knowing they were sinning.
He is not like those other priests. They had to offer sacrifices every day, first for their own sins, and then for the sins of the people. But Jesus doesn’t need to do that. He offered only one sacrifice for all time. He offered himself.
Then Moses told Aaron: “Go do what the Lord commanded. Go to the altar and offer sin offerings and burnt offerings. Do what will make you and the people pure. Take the people’s sacrifices and make them pure.”
