Exodus 30:20
Brenton's English Septuagint · Berean Standard Bible
Whensoever they shall go into the tabernacle of witness, they shall wash themselves with water, so they shall not die, whensoever they advance to the altar to do service and to offer the whole burnt-offerings to the Lord.
Whenever they enter the Tent of Meeting or approach the altar to minister by presenting a food offering to the LORD, they must wash with water so that they will not die.
