Isaiah
Isaiah 66:20ESV·traditional attribution

And 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.

Matthew Henry Presbyterian @wholebiblehenry

These verses, like the pillar of cloud and fire, have a dark side towards the enemies of God's kingdom and all that are rebels against his crown, and a bright side towards his faithful loyal subjects. Probably they refer to the Jews in captivity in Babylon, of whom some are said to have been sent thither for their hurt, and with them God here threatens...

John Gill Reformed Baptist @doctorgill

And they shall bring all your brethren, for an offering unto the Lord, out of all nations,.... This is not said of the Jews, either with respect to the first times of the Gospel; not of the devout men of all nations that heard the apostles on the day of Pentecost; nor of those the Gospel met with in the Gentile world, by the ministry...

they--the Gentiles (Isa 66:19). bring . . . your brethren--the Jews, back to the Holy Land (Isa 49:22). It cannot mean the mere entrance of the Jews into the Christian Church; for such an entrance would be by faith, not upon "horses, litters, and mules" [HOUBIGANT]. "Offering" is metaphorical, as in Rom 15:16. horses--not much used by the Jews.
