'Allowance' in the Bible

Then the Lord spoke to Aaron, “Now behold, I [the Lord] have entrusted you with My heave offerings, even all the holy gifts of the Israelites, I have given them to you as a portion, and to your sons as a continual allotment.

This also is yours: the heave offering of their gift, including all the wave offerings of the Israelites. I have given them to you and to your sons and to your daughters with you as a continual allotment; everyone in your household who is [ceremonially] clean may eat it.
