Proverbs 11:9 (ESV)

9 With his mouth the godless man would destroy his neighbor, but by knowledge the righteous are delivered.

The godless man has no blessing in his heart and brings no blessing through his mouth. Rather, he wants to promote himself by destroying others. The righteous, in particular, are his targets. Yet the righteous are saved, not by directly fighting against the malicious liars, but by their close commitment to the Lord, who gives them knowledge more than sufficient to neutralize godless threats. The psalmist, in the long psalm, repeatedly testifies to this: Even though princes sit and talk against me, Thy servant meditates on Thy statutes. (Psalm 119:23). When we make our devotion to the Lord to be our priority, He makes it His priority to deliver us from all destructive plans against us.
