Isaiah 66:20-21
66:20 They will bring back all your countrymen from all the nations as an offering to the Lord. They will bring them on horses, in chariots, in wagons, on mules, and on camels to my holy hill Jerusalem,” says the Lord, “just as the Israelites bring offerings to the Lord’s temple in ritually pure containers.
66:21 And I will choose some of them as priests and Levites,” says the Lord.
