Numbers 18:29

²⁷And your heave offerings shall be reckoned to you as corn from the floor, and an offering from the winepress.

²⁸So shall ye also separate them from all the offerings of the Lord out of all your tithes, whatsoever ye shall receive from the children of Israel; and ye shall give of them an offering to the Lord to Aaron the priest.

— Numbers 18:29 —

³⁰And thou shalt say to them, When ye shall offer the firstfruits from it, then shall it be reckoned to the Levites as produce from the threshing floor, and as produce from the winepress.

³¹And ye shall eat it in any place, ye and your families; for this is your reward for your services in the tabernacle of witness.
