Proverbs 18: 21 (New King James Version)

Another translation says "those who love to talk, will eat their own words". Which is basically saying you shall reap the actions in which you sew towards other people. I love this scripture because it personifies the power & strength that words have. The Bible uses the tongue to symbolize words, and in doing so, says that life and death are at your own discretion. If you curse and slander the names of people; expect to reap the same actions done to yourself. If you bless and commend other people; you shall reap that nature as well.
