Exodus 30:19-21 ▼

19 And Aaron and his sons shall wash their hands and their feet from it;

20 when they come into the tent of meeting, they shall wash with water, so that they will not die; or when they approach the altar to minister, by offering up in smoke a fire sacrifice to Yahweh.

21 So they shall wash their hands and their feet, so that they will not die; and it shall be a perpetual statute for them, for Aaron and his seed throughout their generations.”
