Mark 13:10

And the Gospel must first be published among all nations. The Syriac version reads, "my Gospel"; the Gospel which Christ was the author, subject, and preacher of; this "must be published". There was a necessity of the promulgation of it by the will of God, the command and commission of Christ; and for the gathering in of the Jews, that were the elect of God, "among all nations" of the world, especially in the Roman empire; and that "first", or before the destruction of Jerusalem; See Gill on Matthew 24:14 .
