On the day that he goes into the holy place, into the inner court, to minister in the holy place, he shall offer his purification offering, says the Lord God.
When they enter the gates of the inner court, they shall wear linen vestments; they shall have nothing of wool on them while they minister at the gates of the inner court and within the temple.
Or when you touch human uncleanness—any uncleanness by which one can become unclean—and are unaware of it, when you come to know it, you shall be guilty.
and you shall bring to the Lord, as your penalty for the sin that you have committed, a female from the flock, a sheep or a goat, as a purification offering, and the priest shall make atonement on your behalf for your sin.
