Isaiah 66:20

And they shall bring all your brethren for an offering unto the LORD out of all nations upon horses, and in chariots, and in litters, and upon mules, and upon swift beasts, to my holy mountain Jerusalem, saith the LORD, as the children of Israel bring an offering in a clean vessel into the house of the LORD.

And they - the Gentiles (Isaiah 66:19 ).

Shall bring all your brethren for an offering unto the Lord, out of all nations, upon horses, and in chariots, and in litters, and upon mules. The Gentiles shall bring the Jews back to the Holy land ( Isaiah 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 a sacrificial metaphor, as in Romans 15:16.

Horses - not much used by the Jews. The Gentiles are here represented as using their modes of conveyance to "bring" the Jews to Jerusalem.

Chariots. As these are not found in Oriental caravans, translate 'vehicles'-namely, borne, not drawn on wheels.

Litters - covered sedans for the rich.

And upon swift beasts - courier's beasts: dromedaries: kirkaarowt (H3753), from a Hebrew root, kaarar ( H3769), to leap, to bound; from their bounding motion, often accelerated by music. (Bochart). Panniers were thrown across the dromedaries' back for poorer women (Horsley).
