Reading the protestant Bible to see if I misremembered anything. (Not so far.) Here's a good one: "If your enemy is hungry, give him food to eat; if he is thirsty, give him water to drink. In doing this, you will heap burning coals on his head, and the Lord will reward you." Proverbs 25:21-22 NIV. It's like God is tricking angry people into being kind.
