Numbers 18:29 Meaning and Commentary

Numbers 18:29

Out of all your gifts ye shall offer every heave offering of
the Lord
Not only out of their tithes, but out of whatsoever gifts were given by the Israelites to them, and out of the produce of the fields which belonged to their cities, ( Numbers 35:4 ) ; the Levites were to take a tenth, and bring it to the Lord as an heave offering; that is, they were to give it to the priests, to testify their gratitude for everything they had, and to sanctify the rest unto them, and confirm their right and title to it, and give them the free use of it:

of all the best thereof, [even] the hallowed part thereof, out of it;
which was the tenth part, for that Was holy, as Aben Ezra says, and that was to be the best of it, which was always to be given to the Lord.

Numbers 18:29 In-Context

27 And your heave-offerings shall be reckoned to you as corn from the floor, and an offering from the wine-press.
28 So 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.
29 Of all your gifts ye shall offer an offering to the Lord, and of every first-fruit the consecrated part from it.
30 And thou shalt say to them, When ye shall offer the first-fruits from it, then shall it be reckoned to the Levites as produce from the threshing-floor, and as produce from the wine-press.
31 And ye shall eat it in any place, ye and your families; for this is your reward for your services in the tabernacle of witness.
