Luke 6:32

³⁰ Give to every man that asketh of thee; and of him that taketh away thy goods ask them not again.

³¹ And as ye would that men should do to you, do ye also to them likewise.

For if ye love them which love you, what thank have ye? for sinners also love those that love them.

³³ And if ye do good to them which do good to you, what thank have ye? for sinners also do even the same.

³⁴ And if ye lend to them of whom ye hope to receive, what thank have ye? for sinners also lend to sinners, to receive as much again.

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