Numbers 18:26

26 Command thou, and announce to the deacons, When ye have taken tithes of the sons of Israel, which I gave to you, offer ye the first fruits of those to the Lord, that is, the tenth part of the tenth, (Command thou, and say to the Levites, When ye have received the tithes of the Israelites, which I gave to you, offer ye the first fruits of those tithes to the Lord, that is, a tithe of the tithe,)

Numbers 18:26 Meaning and Commentary

Numbers 18:26

Thus speak unto the Levites, and say unto them
Aaron was to tell them what a provision would be made for them on account of their service, but Moses was to inform them what part Aaron was to have out of it:

when ye take of the children of Israel the tithes which I have given
you from them for your inheritance;
which was done at the time of their harvest, and of the ingathering of the fruits of the earth:

then ye shall offer up an heave offering of it for the Lord;
in token of gratitude for the liberal provision he had made for the maintenance of them:

[even] a tenth [part] of the tithe;
a tenth part out of the tenth of the produce of the land of Israel.

Numbers 18:26 In-Context

24 They shall wield none other thing, and they shall be satisfied with the offering of tithes, which I separated into [the] uses and necessaries of them. (They shall possess nothing else, and they shall be satisfied with the offering of the tithes which I set apart for their uses and their necessities.)

25 And the Lord spake to Moses and said,

26 Command thou, and announce to the deacons, When ye have taken tithes of the sons of Israel, which I gave to you, offer ye the first fruits of those to the Lord, that is, the tenth part of the tenth, (Command thou, and say to the Levites, When ye have received the tithes of the Israelites, which I gave to you, offer ye the first fruits of those tithes to the Lord, that is, a tithe of the tithe,)

27 that it be areckoned to you into [the] offering of the first fruits, as well of the cornfloors, as of the presses; (so that it shall be counted for you as though it be an offering of the first fruits, yea, from the threshing floor, and from the winepress;)

28 and of all things of which ye take tithes, offer ye the first fruits to the Lord, and give ye those to Aaron, the priest.
