Numbers 18:27 WBT

²⁵  And the LORD spoke to Moses, saying,

²⁶  Thus speak to the Levites, and say to them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up a heave-offering of it for the LORD, [even] a tenth [part] of the tithe.

²⁷  And [this] your heave-offering shall be reckoned to you, as though [it were] the corn of the threshing-floor, and as the fullness of the wine-press.

²⁸  Thus ye also shall offer a heave-offering to the LORD of all your tithes which ye receive of the children of Israel; and ye shall give of them the LORD'S heave-offering to Aaron the priest.

²⁹  Out of all your gifts ye shall offer every heave-offering of the LORD, of all the best of it, [even] its hallowed part out of it.
