'Portion' in the Bible

Then Yahweh said to Moses, "Behold, I will rain bread from the sky for you, and the people shall go out and gather a day's portion every day, that I may test them, whether they will walk in my law, or not.

"You shall take the breast of Aaron's ram of consecration, and wave it for a wave offering before Yahweh: and it shall be your portion.

and it shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering: and it shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to Yahweh.
