Ezekiel 44:7; Ezekiel 44:9

7 when you brought in foreigners , uncircumcised in heart and uncircumcised in flesh, to be in My sanctuary to profane it, even My house, when you offered My food, the fat and the blood; for they made My covenant void -this in addition to all your abominations.

9 'Thus says the Lord GOD, "No foreigner uncircumcised in heart and uncircumcised in flesh, of all the foreigners who are among the sons of Israel, shall enter My sanctuary.
