After he is defiled, he shall count for himself seven days, and then he shall be clean.
And on the day that he goes into the holy place, into the inner court, to minister in the holy place, he shall offer his sin offering, says the Lord God.
Whoever in the open field touches one who is slain with a sword, or a dead body, or a bone of a man, or a grave, shall be unclean seven days.
