Adam Clarke on Zechariah 8:23

Ten men - shall take hold of the skirt of him that is a Jew - The converts from among the Gentiles shall be to the Jews as ten to one. But ten may here signify a great number, without comparison. And from this scripture it appears as if the Jews, converted to God, should be the instruments of converting many Gentiles. See on Isa 3:6 (note). Catching hold of the skirt is a gesture naturally used to entreat assistance and protection. This and the three foregoing verses, says Abp. Newcome, refer to the great accession of converts which the Jewish Church received between the captivity and the coming of Christ; to the number of Christian disciples which the Jewish preachers made, and to the future conversions of which the restoration of the Jews will be an eminent cause.
