Exodus 30:18-20

Modern English Version

¹⁸ You must also make a basin of bronze, with its base also of bronze, for washing, and you must put it between the tent of meeting and the altar, and you must put water in it. ¹⁹ For Aaron and his sons must wash their hands and their feet from it. ²⁰ When they go into the tent of meeting, or when they come near the altar to minister by burning incense as an offering made by fire to the Lord, they must wash with water so that they will not die.
