49:1-6 The great Author of redemption shows the authority for his work. The sword of his word slays the lusts of his people, and all at enmity with them. His sharp arrows wound the conscience; but all these wounds will be healed, when the sinner prays to him for mercy.

Horsley explains, "Notwithstanding the incredulity of the Jews, Messiah shall be glorified in the conversion of the Gentiles," reading as English Version: but if the Keri be read, "Israel shall at one time or other be gathered, notwithstanding their incredulity during Messiah's sojourn on earth."
