Aaron and his sons are to eat the meat of the ram and the bread that was in the basket at the entrance of the tent of meeting.

If any of the meat from the consecration offerings ¹  or any of the bread is left over ²  until morning, then you are to burn up ³  what is left over. It must not be eaten, ⁴  because it is holy.

When ¹  the Israelites saw it, they said to one another, ²  “What is it?” because they did not know what it was. ³  Moses said to them, “It is the bread ⁴  that the Lord has given you for food. ⁵ 

Moses said, “This is what ¹  the Lord has commanded: ‘Fill an omer with it to be kept ²  for generations to come, ³  so that they may see ⁴  the food I fed you in the desert when I brought you out from the land of Egypt.’”

So Moses said to Joshua, “Choose some of our ¹  men and go out, fight against Amalek. Tomorrow I will stand on top of the hill with the staff of God in my hand.”
