Misinterpretations of Isaiah 66:20 often include taking it hyper-literally as predicting end-times transportation by horses and mules in a futuristic scenario, ignoring its symbolic imagery of divine gathering; viewing it solely as fulfilled in the post-exilic return from Babylon, which overlooks the eschatological context of chapters 65-66; or using it to advocate perpetual animal sacrifices in a rebuilt temple, contradicting the New Testament's portrayal of Christ's once-for-all offering that renders such rituals obsolete.
Isaiah 66:20
King James Version (1769)
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.
Isaiah 66:20 prophesies a future gathering of God's people from all nations to Jerusalem, where Gentiles will reverently transport Jewish exiles on various conveyances as a pure offering to the Lord, symbolizing the universal scope of salvation, the inclusion of all peoples in worship, and the ultimate restoration of Israel in the messianic age, fulfilling God's promise of global reconciliation and holiness on His holy mountain.
