Leviticus 16:17

17 "No one can be in the Tent of Meeting when Aaron goes into the Most Holy Room to pay for the people's sin. No one can enter the tent until Aaron comes out. He will not come out until he has paid for his own sin and the sin of his whole family. He will not come out until he has also paid for the sin of the whole community of Israel.

Leviticus 16:17 Meaning and Commentary

Leviticus 16:17

And there shall be no man in the tabernacle of the
congregation
Not any of the priests, as Aben Ezra, no, not in the holy place where they ministered, nor in the court of the tabernacle, nor in any of the courts, nor indeed any of the people: all places were cleared

when he,
the high priest,

goeth in to make an atonement in the holy [place] until he come out;
this in the mystery of it was to signify, that atonement for sin is made only by Christ our high priest; he himself, and no other, bore our sins, and he himself purged them away, or by his sacrifice alone expiated them; his own arm wrought salvation, and of the people there were none with him to help and assist him; when he the Shepherd was smitten by the sword of justice, the sheep were scattered, all his disciples forsook him and fled; there were none to appear for him, or stand by him, or in the least to lend an assisting hand in the great work in which he was engaged; he is the only Mediator, between God and man, both of redemption and of intercession; he is the alone Saviour, to him only are sinners to look for salvation, and he is to have all the glory; he had no partner in the work, and he will have no rival in the honour of it:

and have made an atonement for himself, and for his household;
his whole family, and all the priests, by the bullock of his sin offering, as Aben Ezra observes, and by carrying in the blood of it within the vail, and sprinkling it there:

and for all the congregation of Israel;
by the goat of their sin offering, as the same writer notes, and doing with the blood of that as with the blood of the bullock; all typical of the atonement of Christ for his mystical self the church; for the whole family and household of God; for the general assembly and church of the firstborn, whose names are written in heaven.

Leviticus 16:17 In-Context

15 "Then Aaron must kill the goat for the sin offering for the people. He must take its blood behind the curtain. There he must do the same thing with it as he did with the bull's blood. He must sprinkle it on the cover of the ark. He must also sprinkle some in front of it.

16 "That is how he will make the Most Holy Room pure. He must do it because the people of Israel are not 'clean.' They have not obeyed me. They have also committed other sins. Aaron must do the same for the Tent of Meeting because it stands in the middle of the camp. And the camp is not 'clean.'

17 "No one can be in the Tent of Meeting when Aaron goes into the Most Holy Room to pay for the people's sin. No one can enter the tent until Aaron comes out. He will not come out until he has paid for his own sin and the sin of his whole family. He will not come out until he has also paid for the sin of the whole community of Israel.

18 "Then he will come out to the altar for burnt offerings. It is in front of the tent where the ark of the LORD is. He will make the altar pure and clean. He will take some of the bull's blood and some of the goat's blood. Then he will put the blood on all of the horns that stick out from the upper four corners of the altar.

19 He will sprinkle some of the blood on it with his finger seven times. He will do it to make the altar pure. He will do it to set it apart from the people of Israel. They are not 'clean.'
