“I will also take some of them as priests and Levites.” The natural reading of this verse is that in Christ’s future kingdom on earth some of the Gentiles will be taken as priests and Levites. This makes sense because many Gentiles will be saved and will be worshiping God (see commentary on John 10:16). Nevertheless, this is so different from what God has done in keeping the priests and Levites to only descendants of Levi (and the priests as only descendants of Aaron) that many scholars think the verse is still somehow speaking of this referring to Israelites becoming priests and Levites. But if God were going to open the priesthood to any Israelite, there seems to be no reason that He would not open it to Gentiles as well.
