Levítico 16:17

17 No one is to be in the tent of meeting from the time Aaron goes in to make atonement in the Most Holy Place until he comes out, having made atonement for himself, his household and the whole community of Israel.

17 And no man may be in the Tent of meeting from the time when Aaron goes in to take away sin in the holy place till he comes out, having made himself and his house and all the people of Israel free from sin.
