(Romans 12:19-21 NIV) Do not take revenge, my friends, but leave room for God's wrath, for it is written: "It is mine to avenge; I will repay," says the Lord. {20} 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." {21} Do not be overcome by evil, but overcome evil with good.

(Proverbs 24:17-18 NIV) Do not gloat when your enemy falls; when he stumbles, do not let your heart rejoice, {18} or the LORD will see and disapprove and turn his wrath away from him.
