Matthew Poole and continuators on Isaiah 66:21

21 And I will take of them for priests, and for Levites , saith the LORD.

Le[illegible: 1+ letters]t the Jews, being assured that the Tribe of Levi, which God anciently chose to minister before him, was among them, should say, Alas if the Gentiles should be brought in, where would they have Priests or Levites? God here by his Prophet tells them, he would provide Priests, he would take of them, of these converted Heathens, for Priests and Levites, that is for Gospel-Ministers, to teach and to instruct People, which was the Priests work of old, Deut. 33. 10. 2 Chron. 17. 7, 9. Mal. 2. 6. (for they are mightily mistaken, that think the Priests amongst the Jews had nothing to do, but to sacrifice and burn incense, which work is ceased,) saith the Prophet, God will find amongst the converted Gentiles those who though they be not of the Tribe of Levi, or House of Aaron, yet shall they do the true work of Priests and Levites.
