15 Now I will most gladly spend and be spent for your lives! If I love you more, am I to be loved less?
Darby
15 Now *I* shall most gladly spend and be utterly spent for your souls, if even in abundantly loving you I should be less loved.
KJV
15 And I will very gladly spend and be spent for you; though the more abundantly I love you, the less I be loved.
