Most holy — Such as were to be eaten only by the priests, and that in the sanctuary. Reserved — That is, such sacrifices or parts of sacrifices as were not burnt in the fire. Render unto me — By way of compensation for a trespass committed against me, in which case a ram was to be offered, which was a most holy thing, and may be particularly designed here.
