'Liar' in the Bible

The judges are to make a careful investigation, and if the witness turns out to be a liar who has falsely accused his brother,

If this is not true, then who can prove me a liarand show that my speech is worthless?

In my alarm I said,“Everyone is a liar.”

A wicked person listens to malicious talk;a liar pays attention to a destructive tongue.

Don’t add to His words,or He will rebuke you, and you will be proved a liar.
