John 4:38

³⁶ And he that reapeth receiveth wages, and gathereth fruit unto life eternal: that both he that soweth and he that reapeth may rejoice together.

³⁷ And herein is that saying 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.

³⁹ And many of the Samaritans of that city believed on him for the saying of the woman, which testified, He told me all that ever I did.

⁴⁰ So when the Samaritans were come unto him, they besought him that he would tarry with them: and he abode there two days.
