Numbers 18:31-32

Wycliffe Bible

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.)
