Exodus 30:19-21 ▼

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

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

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