Ezekiel 44:8-10

Young's Literal Translation

⁸ and ye have not kept the charge of My holy things, and ye set [them] for keepers of My charge in My sanctuary for you.

⁹ `Thus said the Lord Jehovah: No son of a stranger, uncircumcised of heart, and uncircumcised of flesh, cometh in unto My sanctuary, even any son of a stranger, who [is] in the midst of the sons of Israel,

¹⁰ but -- the Levites who have gone far off from me, in the wandering of Israel when they went astray from Me after their idols, and they have borne their iniquity.
