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.
