Proverbs 11:9
With his mouth the godless destroys his neighbor, but through knowledge the righteous escape.

One of the identifying marks of the hypocrite is that they destroy people with their words. Sincere love looks to build others up, not to destroy them.

God's deliverance comes to the righteous through their knowledge, both in the sense of wisdom and in the sense of personal relationship with God.

If anyone considers himself religious and yet does not keep a tight rein on his tongue, he deceives himself and his religion is worthless. (James 1:26)

Application

If you have hurted anyone with your words recently, go and reconcile with them.
