John Wesley on Deuteronomy 32:14

Fat of lambs - For though the fat wherewith the inward parts were covered was not to be eaten by them, but offered to God, yet that fat which was mixed with the flesh they might eat, as the Jewish doctors note. Basham - A place famous for excellent cattle. Fat of kidneys of wheat - With the finest of the grains of wheat; compared to kidneys for their shape and largeness.
