Exodus 30:20

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:

When they go into the tent of meeting, they shall wash with water, that they not die; or when they come near to the altar to minister, to burn an offering made by fire to Yahweh.

when they go into the tent of meeting, they shall wash with water, that they die not; or when they come near to the altar to minister, to burn an offering made by fire unto Jehovah.

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,

Whenever they enter the Tent of Meeting or approach the altar to minister by presenting an offering made by fire to the LORD, they must wash with water so that they will not die.
