Ezekiel 44:7, 9

When you brought in foreigners, uncircumcised in heart and uncircumcised in flesh, to be in My sanctuary to defile it—My house—and when you offered My food, the fat and the blood, then they broke My covenant because of all your abominations.

Thus says the Lord GOD: “No foreigner, uncircumcised in heart or uncircumcised in flesh, shall enter My sanctuary, including any foreigner who is among the children of Israel.
