John Calvin on Acts 13:49

49. The word of the Lord was spread abroad. Luke doth in this place declare the proceeding “Progressum,” the progress. of the gospel; wherein appeareth how true the parable of Christ is, when he saith that it is like to leaven, (Luke 13:21.) We heard before that there was great concourse of people, so that the seed of true doctrine was sown throughout the whole city. Luke saith now that it was spread farther, to wit, throughout the whole country.
