³³He that of Aarons sones offrith the blood, and the ynnere fatnesse, schal haue also the riyt schuldur in his porcioun.

³⁴For Y haue take fro the sones of Israel the brest of reisyng, and the schuldur of departyng, of the pesible sacrifices `of hem, and Y haue youe to Aaron the preest and to hise sones, bi euerlastynge lawe, of al the puple of Israel.
