Isaiah 66:20-23

20And they shall bring all your brothers from all the nations as an offering to the Lord, on horses and in chariots and in litters and on mules and on dromedaries, to my holy mountain Jerusalem, says the Lord, just as the Israelites bring their grain offering in a clean vessel to the house of the Lord.

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

22"For as the new heavens and the new earth that I make shall remain before me, says the Lord, so shall your offspring and your name remain.

23From new moon to new moon, and from Sabbath to Sabbath, all flesh shall come to worship before me, declares the Lord.
