Ezekiel 44:4-16 New Revised Standard Version, Anglicised (NRSVA)
Admission to the Temple
4 Then he brought me by way of the north gate to the front of the temple; and I looked, and lo! the glory of the Lord filled the temple of the Lord; and I fell upon my face. 5 The Lord said to me: Mortal, mark well, look closely, and listen attentively to all that I shall tell you concerning all the ordinances of the temple of the Lord and all its laws; and mark well those who may be admitted to[a] the temple and all those who are to be excluded from the sanctuary. 6 Say to the rebellious house,[b] to the house of Israel, Thus says the Lord God: O house of Israel, let there be an end to all your abominations 7 in admitting foreigners, uncircumcised in heart and flesh, to be in my sanctuary, profaning my temple when you offer to me my food, the fat and the blood. You[c] have broken my covenant with all your abominations. 8 And you have not kept charge of my sacred offerings; but you have appointed foreigners[d] to act for you in keeping my charge in my sanctuary.
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. 12 Because they ministered to them before their idols and made the house of Israel stumble into iniquity, therefore I have sworn concerning them, says the Lord God, that they shall bear their punishment. 13 They shall not come near to me, to serve me as priest, nor come near any of my sacred offerings, the things that are most sacred; but they shall bear their shame, and the consequences of the abominations that they have committed. 14 Yet I will appoint them to keep charge of the temple, to do all its chores, all that is to be done in it.
The Levitical Priests
15 But the levitical priests, the descendants of Zadok, who kept the charge of my sanctuary when the people of Israel went astray from me, shall come near to me to minister to me; and they shall attend me to offer me the fat and the blood, says the Lord God. 16 It is they who shall enter my sanctuary, it is they who shall approach my table, to minister to me, and they shall keep my charge.
