They shall wash their hands and their feet, lest they die: it shall be a statute for ever to them, even to him and to his descendants throughout their generations.”
In the tent of meeting, outside the veil which is before the testimony, Aaron and his sons shall tend it from evening to morning before the Lord. It shall be a statute for ever to be observed throughout their generations by the people of Israel.
and they shall be upon Aaron, and upon his sons, when they go into the tent of meeting, or when they come near the altar to minister in the holy place; lest they bring guilt upon themselves and die. This shall be a perpetual statute for him and for his descendants after him.
When they go into the tent of meeting, or when they come near the altar to minister, to burn an offering by fire to the Lord, they shall wash with water, lest they die.
