'Of the Flesh' in the Bible

Because they are only rules of the flesh, of meats and drinks and washings, which have their place till the time comes when things will be put right.

For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:

than the sacrificers had to eat of the flesh of those beasts, which were burnt without the camp, and whose blood the highpriest carried into the sanctuary.
