False Witness: Why Our Words Matter The Power of Our Words Our words carry great power—they can uplift, heal, and encourage relationships or hurt, mislead, and destroy them. Bearing false witness, or speaking falsely about others, is so harmful that it is directly prohibited in the Bible as one of God’s Ten Commandments: “You shall not bear false witness against your neighbour” (Exodus 20:16, WEB). This commandment emphasizes our words’ profound impact, urging us to speak truthfully and kindly at all times.
