'Portion' in the Bible

Yahweh spoke to Aaron, "Behold, I myself have given to you the responsibility of my contributions for all the holy objects of the {Israelites}; I have given them as a portion to you and your sons as an eternal decree.

And the cities that you will give from the property of the {Israelites}, you will take more from the larger group and less from the smaller group; each of them will give according to the portion of their inheritance according to the portion that he inherits."
