A thing most holy - literally, a holy of holies. All offerings were holy, including the portions of the peace-offerings which were eaten by the laity; but that was “most holy” of which every part was devoted either to the altar, or to the use of the priests. Such were the minchaahs, the showbread, the incense, and the flesh of the sin-offerings and trespass-offerings. Compare the similar distinction between places Exodus 26:33. The most holy food was eaten in “the holy place,” that is the precinct of the tabernacle, probably in the priests’ lodgings; but the priests’ portion of the peace-offerings might be eaten by the priests and their families in any “clean place” Leviticus 10:12-14.
