Exodus 40:31 In-Context

29 And at the door of the House of the Tent of meeting, he put the altar of burned offerings, offering on it the burned offering and the meal offering, as the Lord had given him orders.

30 And between the altar and the Tent of meeting he put the vessel with water in it for washing.

31 In it the hands and feet of Moses and Aaron and his sons were washed,

32 Whenever they went into the Tent of meeting, and when they came near the altar, as the Lord had given orders to Moses.
