On the contrary: "If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head."
NIV
But if your enemy is hungry, feed him; if he is thirsty, give him drink; for by so doing you will heap burning coals upon his head. [Prov. 25:21, 22.]AMP
Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
KJV
