Exodus 40:30-32

Young's Literal Translation

³⁰ And he putteth the laver between the tent of meeting and the altar, and putteth water there for washing,

³¹ and Moses and Aaron and his sons have washed their hands and their feet at the same;

³² in their going in unto the tent of meeting, and in their drawing near unto the altar, they wash, as Jehovah hath commanded Moses.
