the bread] The shew-bread, or meat-offerings; or all the food that came, by way of Oblation, to the Priests his servants, might be called bread; for in Scripture, whatsoever serveth for mans sustenance, is often so called; See vers. 17. 21.
therefore] Holinesse is pressed upon the Priests in especiall manner, because they must both by doctrine, and example, worke upon the people to be holy also; and if they be profane, their scandalous lives bring contempt on the name, and service of God, as if they were profane or common things.
holy] Hebr. holinesse in the abstract; importing an extraordinary degree of holinesse; as if they should not be carnall at all, but meere spirituall, all holy, even as holinesse it self.
