Bible Verses About Purifications: Of high priest on day of atonement

He shall be vested with a linen tunick: he shall cover his nakedness with linen breeches: he shall be girded with a linen girdle, and he shall put a linen mitre upon his head. For these are holy vestments: all which he shall put on, after he is washed.

He shall wash his flesh in the holy place, and shall put on his own garments. And after that he is come out and hath offered his own holocaust, and that of the people, he shall pray both for himself, and for the people.
