Ezequiel 44:9

9 This 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.

9 Thus saith the Lord Jehovah, No foreigner, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any foreigners that are among the children of Israel.
