The purpose and meaning of the Ninth Commandment
How important is truth? To fully appreciate the Ninth Commandment with its prohibition of lying, we must realize how important truth is to God.
You shall not bear false witness against your neighbour. Exodus 20:16
What do the Scriptures tell us about God, His Word and truth? Notice what several verses tell us: Every word of God is pure
Proverbs 30:5. Daniel refers to God's Word as the Scripture of Truth. Daniel 10:21. Jesus Christ said of God the Father, Your word is truth. John 17:17
The Bible throughout teaches that God is not a man, that he should lie. Numbers 23:19. It explains that the word of the LORD is right; and all his works are done in truth. (Psalms 33:4) because He is a God of truth. Deuteronomy 32:4. And His truth endureth to all generations. Psalms 100:5
As the source of truth, God requires that His servants always speak truthfully. Under God's inspiration, King David writes, Lord, who may dwell in your sanctuary? Who may live on your holy hill? He whose walk is blameless and who does what is righteous, who speaks the truth from his heart and has no slander on his tongue, who does his neighbour no wrong and casts no slur on his fellow-man
[and] who keeps his oath even when it hurts. Psalms 15:1-3. God expects truth to permeate every facet of our lives.
