Levítico 8:31

31 Moses then said to Aaron and his sons, "Cook the meat at the entrance to the tent of meeting and eat it there with the bread from the basket of ordination offerings, as I was commanded: 'Aaron and his sons are to eat it.'

31 And Moses said to Aaron and to his sons, The flesh is to be cooked in water at the door of the Tent of meeting, and there you are to take it as food, together with the bread in the basket, as I have given orders, saying, It is the food of Aaron and his sons.
