Proverbs 25:18-22

Telling lies about others is as harmful as hitting them with an ax, wounding them with a sword, or shooting them with a sharp arrow. Putting confidence in an unreliable person in times of trouble is like chewing with a broken tooth or walking on a lame foot. Singing cheerful songs to a person with a heavy heart is like taking someone’s coat in cold weather or pouring vinegar in a wound. If your enemies are hungry, give them food to eat. If they are thirsty, give them water to drink. You will heap burning coals of shame on their heads, and the LORD will reward you.
