Remigius of Auxerre
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.
For the number of the Apostles was small in comparison of so great crops to be reaped. The Lord exhorts His preachers, that is, the Apostles and their followers, that they should daily desire an increase of their number; Pray ye therefore the Lord of the harvest, that he would send forth labourers into his harvest.
