'Portion' in the Bible

Then the Lord said to Moses, “Behold, I will rain bread from heaven for you; and the people shall go out and gather a day’s portion every day, that I may test them, whether or not they will walk in My instruction.

“Then you shall take the breast of Aaron’s ram of ordination, and wave it as a wave offering before the Lord; and it shall be your portion.

It shall be for Aaron and his sons as their portion forever from the sons of Israel, for it is a heave offering; and it shall be a heave offering from the sons of Israel from the sacrifices of their peace offerings, even their heave offering to the Lord.
