Romans 11:25,26

I would not have you ignorant, brethren, of this mystery, this hidden truth of God's justice and mercy, that blindness in part hath happened in Israel, or to part of them, until the fulness of the Gentiles should come in, by the conversion of all nations: and then all Israel should be saved, when they shall submit to the faith of Christ: as it is written by the prophet Isaias, (lix. 20.) there shall come out of Sion he that shall deliver; that is, their Redeemer, Christ Jesus, who is indeed come already, but who shall then come to them by his powerful grace. This is my covenant with them. (Witham)
