Leviticus 7:29-32

²⁹and seide, Speke thou to the sones of Israel, He that offrith a sacrifice of pesible thingis to the Lord, offre togidere also a sacrifice, that is, fletynge offryngis therof.

³⁰He schal holde in the hondis the ynnere fatnesse of the sacrifice, and the brest; and whanne he hath halewid bothe offrid to the Lord, he schal yyue to the preest,

³¹which schal brenne the ynnere fatnesse on the auter; sotheli the brest schal be Aarons and hise sones;

³²and the riyt schuldur of the sacrifices of pesible thingis schal turne in to the firste fruytis of the preest.
