A man's belly shall be satisfied with the fruit of his mouth; [and] with the increase of his lips shall he be filled. Death and life [are] in the power of the tongue: and they that love it shall eat the fruit thereof. (Proverbs 18:20-21 KJV)
Same verses with the Good News Bible translation:
You will have to live with the consequences of everything you say.
What you say can preserve life or destroy it; so you must accept the consequences of your words.
