'Portion' in the Bible

And the Lord said, Who then is the faithful and wise steward, whom his lord shall set over his household, to give them their portion of food in due season?

the lord of that servant shall come in a day when he expecteth not, and in an hour when he knoweth not, and shall cut him asunder, and appoint his portion with the unfaithful.

and the younger of them said to his father, Father, give me the portion of thy'substance that falleth to me. And he divided unto them his living.
