perpetual <05769> [a perpetual.]

That is, neither the blood which is contained in the larger veins and arteries, nor the fat or suet which is within the animal, which exists in a separate or unmixed state, as the {omentum} or {caul,} the fat of the {mesentery,} or fatty part of the substance which connects the convolutions of the alimentary canal or small intestines, the fat of the kidneys, and whatever else of the internal fat was easily separable, together with the whole of the tail already described; for the blood which assumes the form of gravy, and the fat which is intermixed with the other flesh, might be eaten. This law not only related to the sacrifices, but to all the cattle which the Israelites slaughtered for food.
