Exodus 40:30-32

New Century Version

³⁰ Moses put the bowl between the Meeting Tent and the altar for burnt offerings, and he put water in it for washing. ³¹ Moses, Aaron, and Aaron’s sons used this water to wash their hands and feet. ³² They washed themselves every time they entered the Meeting Tent and every time they went near the altar for burnt offerings, just as the Lord commanded Moses.
