'Liar' in the Bible

If this weren't so, who can prove that I'm a liar by showing that there's nothing to what I'm saying?"

A deceitful person will not sit in my house; A liar will not remain in my presence.

Whoever conceals hatred is a deceitful liar, and whoever spreads slander is a fool.

A truthful saying is trusted forever, but the liar only for a moment.

Whoever practices evil pays attention to wicked speech, and the liar listens to malicious talk.

Don't add to his words, or he will rebuke you, and you will be shown to be a liar.
