John Chrysostom
Catena Aurea · Johannesevangelium 4
Say not ye, There are yet four months, and then cometh harvest? behold, I say unto you, Lift up your eyes, and look on the fields; for they are white already to harvest. And he that reapeth receiveth wages, and gathereth fruit unto life eternal: that both he that soweth and he that reapeth may rejoice together. And herein is that saving true, One soweth, and another reapeth. I sent you to reap that whereon ye bestowed no labour: other men laboured, and ye are entered into their labours.
(Hom. xxxiv. 2) He confirms what He says by a proverb, And herein is that saying true, one soweth and another reapeth, i. e. one party has the labour, and another reaps the fruit. The saying is especially applicable here, for the Prophets had laboured, and the disciples reaped the fruits of their labours: I sent you to reap that whereon ye bestowed no labour.
