Proverbs 12:17 (NKJV) — 17 He who speaks truth declares righteousness, But a false witness, deceit.
The relationship between words and character. Words reveal inner character. They either display righteousness or deceitfulness. One who speaks the truth demonstrates righteousness; a false witness reveals deceitfulness. The term “false witness” specifically describes someone who gives an untrue report about the activities of another. This sin is prohibited in the Ten Commandments (Exodus 20:16).
