Ezekiel 44:7-8

7, 8. Strangers, uncircumcised in heath and uncircumcised in flesh These “aliens” (R.V.) were not excluded from entering the temple and offering sacrifices to Jehovah in their own behalf (Leviticus 17:8; Leviticus 17:10; Leviticus 17:12; Numbers 15:14; Numbers 15:29), but foreigners (probably slaves or captives in war), who had no sympathy whatever with the Israelitish religion, ought not to be permitted to take official positions in Jehovah’s house, as had sometimes been done (Joshua 9:27; 1 Samuel 2:13; Zechariah 14:21; Ezra 2:58, Hebrews). Service with the lip or the hand only is an abomination to God. Even otherwise menial services become sacred when done for Jehovah, and it is an insult to him when such services are put upon ignorant and impure foreigners who have no heart loyalty to the lord of the house. (Compare W.R. Smith, Old Testament in the Jewish Church, pp. 260-266.) It was practically breaking covenant with Jehovah to set them as keepers of my charge in my sanctuary (Ezekiel 44:8).
