John Chrysostom
Catena Aurea · Matthäusevangelium 9
But when he saw the multitudes, he was moved with compassion on them, because they fainted, and were scattered abroad, as sheep having no shepherd. Then saith he unto his disciples, The harvest truly is plenteous, but the labourers are few; Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest.
He privately insinuates Himself to be the Lord; for it is He Himself who is Lord of the harvest. For if He sent the Apostles to reap what they had not sown, it is manifest that He sent them not to reap the things of others, but what He had sown by the Prophets. But since the twelve Apostles are the labourers, He said, Pray ye the Lord of the harvest, that he would send labourers into his harvest; and notwithstanding He added none to their number, but rather He multiplied those twelve many times, not by increasing their numbers, but by giving them more abundant grace.
