Numbers 18:28-30

Darby Translation

²⁸ Thus ye also shall offer Jehovah's heave-offering of all your tithes, which ye take of the children of Israel; and ye shall give thereof Jehovah's heave-offering to Aaron the priest.

²⁹ Out of all that is given you ye shall offer the whole heave-offering of Jehovah,—of all the best thereof the hallowed part thereof.

³⁰ And thou shalt say unto them, When ye heave the best thereof from it, then it shall be counted unto the Levites as produce of the threshing-floor, and as produce of the winepress.
