You are to eat it as a most holy offering, and every male may eat it. You shall regard it as holy. / And this is yours as well: the offering of their gifts, along with all the wave offerings of the Israelites.

Every ceremonially clean person in your household may eat it. / 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.
