19 And not that only, but who was also chosen of the churches to travel with us with this grace, which is administered by us to the glory of the same Lord, and declaration of your ready mind:
Then he makes him respected also from the judgment of those that had chosen him. And this too is no light matter. Therefore after saying, "Whose praise in the Gospel is spread through all the churches," he added, "And not only so." What is, "and not only so?" 'Not only on this account,' he says, 'is respect due to him, that he is approved as a preacher and is praised by all.' "But he was also appointed by the churches along with us." Whence it seems to me, that Barnabas is the person intimated. And he signifies his dignity to be great, for he shows also for what office he was appointed. For he saith, "To travel with us in the matter of this grace which is ministered by us." Seest thou how great are these praises of him? He shone as a preacher of the Gospel and had all the churches testifying to this. He was chosen by us; and unto the same office with Paul, and everywhere was partner with him, both in his trials and in his dangers, for this is implied in the word "travel." But what is, "with this grace which is ministered by us?" So as to proclaim the word, he means, and to preach the Gospel; or to minister also in respect of the money; yea rather, he seems to me to refer to both of these. Then he adds, "To the glory of the same Lord, and to show your readiness." What he means is this: 'We thought good,' he says, 'that he should be chosen with us and be appointed unto this work, so as to become a dispenser and a minister of the sacred money.' Nor was this a little matter. For, "Look ye out," it saith, "from among you seven men of good report;" and he was chosen by the churches, and there was a vote of the whole people taken.
