Whoso rewardeth evil for good, evil shall not depart from his house.
– Proverbs 17:13
This proverb also relies on the principle of sowing and reaping. Rewarding evil for good is to be ungrateful and churlish (1 Samuel 25:21). The reaping is given in the second phrase. The word for evil can be moral or natural. Either way, the evil done comes home to roost (Proverbs 13:21). Wisdom and faith teach the opposite behavior (Proverbs 3:30; 20:22; 1 Peter 3:9). Jesus taught to repay good for evil (Matthew 5:43-48).
