Ezekiel 44:9-16

9This is what the Sovereign Lord says: No foreigner uncircumcised in heart and flesh is to enter my sanctuary, not even the foreigners who live among the Israelites. 10“ ‘The Levites who went far from me when Israel went astray and who wandered from me after their idols must bear the consequences of their sin. 11They may serve in my sanctuary, having charge of the gates of the temple and serving in it; they may slaughter the burnt offerings and sacrifices for the people and stand before the people and serve them. 12But because they served them in the presence of their idols and made the people of Israel fall into sin, therefore I have sworn with uplifted hand that they must bear the consequences of their sin, declares the Sovereign Lord. 13They are not to come near to serve me as priests or come near any of my holy things or my most holy offerings; they must bear the shame of their detestable practices. 14And I will appoint them to guard the temple for all the work that is to be done in it. 15“ ‘But the Levitical priests, who are descendants of Zadok and who guarded my sanctuary when the Israelites went astray from me, are to come near to minister before me; they are to stand before me to offer sacrifices of fat and blood, declares the Sovereign Lord. 16They alone are to enter my sanctuary; they alone are to come near my table to minister before me and serve me as guards.
