'Liar' in the Bible

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.

A wicked doer giveth heed to false lips; and a liar giveth ear to a naughty tongue.

The desire of a man 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.
