Albert Barnes Commentary Proverbs 14:25

"A true witness delivereth souls; But he that uttereth lies [causeth] deceit." — Proverbs 14:25 (ASV)

In the second clause, “destroys life” might have been expected as the antithesis to delivereth souls. But what worse could be said? A deceitful witness speaketh lies. All destruction is implied in falsehood.
