Isaiah 66:20-21

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

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