Exodus 30:19-21

Young's Literal Translation

¹⁹ and Aaron and his sons have washed at it their hands and their feet,

²⁰ in their going in unto the tent of meeting they wash [with] water, and die not; or in their drawing nigh unto the altar to minister, to perfume a fire-offering to Jehovah,

²¹ then they have washed their hands and their feet, and they die not, and it hath been to them a statute age-during, to him and to his seed to their generations.'
