Esias 66:21 In-Context

19 And I will leave a sign upon them, and I will send forth them that have escaped of them to the nations, to Tharsis, and Phud, and Lud, and Mosoch, and to Thobel, and to Greece, and to the isles afar off, to those who have not heard my name, nor seen my glory; and they shall declare my glory among the Gentiles.
20 And they shall bring your brethren out of all nations for a gift to the Lord with horses, and chariots, in litters mules with awnings, to the holy city Jerusalem, said the Lord, as though the children of Israel should bring their sacrifices to me with psalms into the house of the Lord.
21 And I will take of them priests and Levites, saith the Lord.
22 For as the new heaven and the new earth, which I make, remain before me, saith the Lord, so shall your seed and your name continue.
23 And it shall come to pass from month to month, and from sabbath to sabbath, all flesh shall come to worship before me in Jerusalem, saith the Lord.
