Proverbs 16:24 says “Pleasant words are like a honeycomb. Sweetness to the soul and health to the bones”
Our words effect us and the people around us in a greater way than we could imagine. Either it can build up somebody or pull down.
Therefore it is wise to think before we speak. The word of God have always been encouraging, comforting and edifying people. In the book of Judges 6:11,12 we see Gideon hiding grains from the Midianites.
