Exodus 30:19-21

KJ2000(i) 19 For Aaron and his sons shall wash their hands and their feet there: 20 When they go into the tabernacle of meeting, they shall wash with water, that they die not; or when they come near to the altar to minister, to burn offering made by fire unto the LORD: 21 So they shall wash their hands and their feet, that they die not: and it shall be a statute forever to them, even to him and to his descendants throughout their generations.
