Isaiah 42:16,17

And I will bring the blind The ignorant Gentiles, represented as blind, Isaiah 42:7, and in many other parts of Scripture, and accounted blind by the Jews; by a way that they knew not By the way of truth, which hitherto hath been hidden from them. I will make darkness light before them, &c. I will enlighten their dark minds, rectify their perverse wills and affections, and direct them in the right way, until I have brought them, with safety and comfort, to the end of their journey. They shall be turned back, &c. This may be understood, either, 1st, Of the converted Gentiles, turned back from their former sinful courses, and sincerely grieving, and being ashamed, that they should ever have been guilty of such folly and wickedness as to worship and trust in idols; or, 2d, Of those Gentiles who, when their brethren embraced the true religion, persisted obstinately in their idolatrous practices.
