John 4:38

³⁶ Already the reaper draws his wages and gathers a crop for eternal life, so that the sower and the reaper may rejoice together.

³⁷ For in this case the saying ‘One sows and another reaps’ is true.

I sent you to reap what you have not worked for; others have done the hard work, and now you have taken up their labor.”

³⁹ Many of the Samaritans from that town believed in Jesus because of the woman’s testimony, “He told me everything I ever did.”

⁴⁰ So when the Samaritans came to Him, they asked Him to stay with them, and He stayed two days.

Do read the surrounding verses too, because the context often says more than a single verse.
