Numbers 18:27-32

²⁷And your heaue offering shalbe reckened vnto you, as the corne of the barne, or as the abundance of the wine presse.

²⁸So ye shall also offer an heaue offring vnto the Lord of all your tithes, which ye shall receiue of the children of Israel, and ye shall giue thereof the Lords heaue offring to Aaron the Priest.

²⁹Ye shall offer of all your gifts al the Lords heaue offrings: of all the fat of the same shall ye offer the holy things thereof.

³⁰Therefore thou shalt say vnto them, When ye haue offred the fat thereof, then it shalbe couted vnto the Leuites, as the encrease of the corne floore, or as the encrease of the wine presse.

³¹And ye shall eate it in al places, ye, and your housholdes: for it is your wages for your seruice in the Tabernacle of the Congregation.

³²And ye shall beare no sinne by the reason of it, when ye haue offred the fatte of it: neither shall ye pollute the holy things of the children of Israel, lest ye die.
