Ezekiel 44:9-11

New Revised Standard Version Catholic Edition

⁹ Thus says the Lord God: No foreigner, uncircumcised in heart and flesh, of all the foreigners who are among the people of Israel, shall enter my sanctuary. ¹⁰ But the Levites who went far from me, going astray from me after their idols when Israel went astray, shall bear their punishment. ¹¹ They shall be ministers in my sanctuary, having oversight at the gates of the temple, and serving in the temple; they shall slaughter the burnt offering and the sacrifice for the people, and they shall attend on them and serve them.
