I give you all the freshest olive oil and all the finest new wine and grain that the Israelites give to the LORD as their firstfruits.

And this shall be the priest's due from the people, from them that offer a sacrifice, whether it be ox or sheep; and they shall give to the priest the shoulder, and the two cheeks, and the maw.
