Ezekiel 44:7

in that ye have brought into My Sanctuary strangers, literally, "children of a stranger," uncircumcised in heart, knowing nothing of repentance and faith, and uncircumcised in flesh, not having even the outward badge of the covenant people, to be in My Sanctuary, for non-Israelites were not permitted to perform the functions of the priesthood, to pollute it, even My house, when ye offer My bread, the sacrificial food placed on the Temple altars, the fat and the blood; and they have broken My covenant because of all your abominations; for since the children of Israel permitted this infraction of the rules of the Lord, it was their act that brought about the desecration of the Sanctuary, and the abomination was laid to their charge.
