When confronted by power, visible profit and love, people sometimes commit a sin and stand for falsity.

In the Bible, bearing ‘false witness’ is included among the seven things that God detests. When small lies add up , we become less sensitive and numb to sin, and this results in greater sin. We must not be dull toward sin but keenly aware. 

The following verses are messages warning against bearing false witness. May the word of God awaken our spirit to discern good and evil, that we may stand upright in the truth.

There are six things the Lord hates, seven that are detestable to him: haughty eyes, a lying tongue, hands that shed innocent blood, a heart that devises wicked schemes, feet that are quick to rush into evil, a false witness who pours out lies and a person who stirs up conflict in the community.

“Are you still so dull?” Jesus asked them. “Don’t you see that whatever enters the mouth goes into the stomach and then out of the body?

   – Matthew 15:16-20 NIV

If a malicious witness takes the stand to accuse someone of a crime, the two people involved in the dispute must stand in the presence of the Lord before the priests and the judges who are in office at the time.

You must purge the evil from among you
   – Deuteronomy 19:16-21 NIV
