'Liar' in the Bible

And if it be not so now, who will prove me a liar, And make my speech nothing worth?

Notwithstanding my right I am accounted a liar; My wound is incurable, though I am without transgression.

An evil-doer giveth heed to wicked lips; And a liar giveth ear to a mischievous tongue.

That which maketh a man to be desired is his kindness; And a poor man is better than a liar.

Add thou not unto his words, Lest he reprove thee, and thou be found a liar.
