'Liar' in the Bible

“Now if it is not so, who can prove me a liar,And make my speech worthless?”

An evildoer listens to wicked lips;A liar pays attention to a destructive tongue.

What is desirable in a man is his kindness,And it is better to be a poor man than a liar.

Do not add to His wordsOr He will reprove you, and you will be proved a liar.

You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.

and you have not come to know Him, but I know Him; and if I say that I do not know Him, I will be a liar like you, but I do know Him and keep His word.

May it never be! Rather, let God be found true, though every man be found a liar, as it is written,“That You may be justified in Your words,And prevail when You are judged.”

If we say that we have not sinned, we make Him a liar and His word is not in us.
