John Gill

And their seed shall be known among the Gentiles, and their offspring among the people,.... Not only the Jews will be converted as a body in the latter day, but there will be a succession of converts among them in later ages, and will be known among Christian Gentiles by their faith and love, and good works and holy conversation; and will be taken notice of and acknowledged by them as brethren, and will be famous among them for religion and godliness: all that see them shall acknowledge them, that they are the seed which the Lord hath blessed; that they are the spiritual seed of Abraham, as well as his carnal seed, and are blessed with him; blessed with all spiritual blessings in Christ, with faith in him, and with every other grace.
