'Portion' in the Bible

Then said Jehovah unto 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 prove them, whether they will walk in my law, or not.

And thou shalt take the breast of Aaron's ram of consecration, and wave it for a wave-offering before Jehovah: and it shall be thy portion.

and it shall be for Aaron and his sons as their portion for ever from the children of Israel; for it is a heave-offering: and it shall be a heave-offering from the children of Israel of the sacrifices of their peace-offerings, even their heave-offering unto Jehovah.
