Exodus 30:19-21

UKJV(i) 19 For Aaron and his sons shall wash their hands and their feet thereat: 20 When they go into the tabernacle of the congregation, 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 for ever to them, even to him and to his seed throughout their generations.
