Numbers 18:11-13

18:11 “And this is yours: the raised offering of their gift, along with all the wave offerings of the Israelites. I have given them to you and to your sons and daughters with you as a perpetual ordinance. Everyone who is ceremonially clean in your household may eat of it.

18:12 “All the best of the olive oil and all the best of the wine and of the wheat, the first fruits of these things that they give to the Lord, I have given to you. 18:13 And whatever first ripe fruit in their land they bring to the Lord will be yours; everyone who is ceremonially clean in your household may eat of it.
