Numbers 18:32

32 And ye shall not do sin on this thing, and reserve [the] noble things and [the] fat to you, lest ye defoul the offerings of the sons of Israel, and ye die. (And ye shall not do sin with these things, and take the noble and the fat things for yourselves, lest ye defile the offerings of the Israelites, for then ye shall die/for then ye must be put to death.)

Numbers 18:32 Meaning and Commentary

Numbers 18:32

And ye shall bear no sin by reason of it
Shall have no blame laid upon them, or guilt imputed to them, or punishment inflicted on them, on account of their having and enjoying their tithes and gifts:

when ye have heaved from it the best of it;
took out the tenth, and that the best, and given it to the priests; or otherwise they would be blameworthy, guilty, and liable to punishment:

neither shall ye pollute the holy things of the children of Israel;
the gifts they have given for holy uses, and so are holy; which would be the case if they ate of them, or enjoyed them, without giving the priests the tenth part of them:

lest ye die;
for it seems such a neglect was punishable with death.

Numbers 18:32 In-Context

30 And thou shalt say to them, If ye offer to the Lord all the [more] clean and better things of tithes, it shall be areckoned to you, as if ye gave the first fruits of the cornfloor, and of the press. (And thou shalt say to them, When ye have offered to the Lord all the more clean and better things of the tithes, it shall be counted for you, like the first fruits from the threshing floor, and from the winepress.)

31 And ye shall eat those tithes in all your places, as well ye as your families, for it is the price for the service, for which ye serve in the tabernacle of witnessing. (And ye shall eat those tithes in all your dwelling places, ye as well as your families, or your households, for it is the payment for the service which ye do, in the Tabernacle of the Witnessing.)

32 And ye shall not do sin on this thing, and reserve [the] noble things and [the] fat to you, lest ye defoul the offerings of the sons of Israel, and ye die. (And ye shall not do sin with these things, and take the noble and the fat things for yourselves, lest ye defile the offerings of the Israelites, for then ye shall die/for then ye must be put to death.)
