Proverbs 25:4-5; Proverbs 25:21-22

4 Remove impurities from the silver and the silversmith can craft a fine chalice; 5 Remove the wicked from leadership and authority will be credible and God-honoring.
21 If you see your enemy hungry, go buy him lunch; if he's thirsty, bring him a drink. 22 Your generosity will surprise him with goodness, and God will look after you.
