'Prescribed' in the Bible
Then the LORD told Aaron, "Look! I am indeed placing you in charge of my raised offerings and the holy things concerning the Israelis. Because of your anointing, I'm giving you and your sons a prescribed portion forever.
The raised offering and wave offerings presented by the Israelis are yours, too. I've given them to you, to your sons, and to your daughters as a prescribed apportionment forever. Everyone who is clean in your household may eat it.
I'm giving you, your sons, and your daughters as a prescribed portion forever all the raised offerings of the consecrated things that the Israelis offer to the LORD. It's a salt covenant forever before the LORD with you and your descendants with you."
This burnt offering, which was prescribed at Mount Sinai, is to be offered every day as a pleasing aroma made by fire to the LORD.
