Ezekiel 44:5-9

5And the Lord said to me, "Son of man, mark well, see with your eyes, and hear with your ears all that I shall tell you concerning all the statutes of the temple of the Lord and all its laws. And mark well the entrance to the temple and all the exits from the sanctuary.

6And say to the rebellious house, to the house of Israel, Thus says the Lord God: O house of Israel, enough of all your abominations,

7in 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 have broken my covenant, in addition to all your abominations.

8And you have not kept charge of my holy things, but you have set others to keep my charge for you 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.
