Isaiah 66:20-21

20Then they shall 1bring all your countrymen from all the nations as a grain offering to the Lord, on horses, in chariots, in litters, on mules, and on camels, to My 2holy mountain Jerusalem,” says the Lord, “just as the sons of Israel bring their grain offering in a 3clean vessel to the house of the Lord.

21I will also take some of them as 4priests and Levites,” says the Lord.
