A wholesome tongue is a tree life.

“Why do you boast in evil, O mighty man? The goodness of God endures continually. Your tongue devises destruction, Like a sharp razor, working deceitfully. You love evil more than good, Lying rather than speaking righteousness. Selah You love all devouring words, You deceitful tongue. God shall likewise destroy you forever; He shall take you away, and pluck you out of your dwelling place, And uproot you from the land of the living. Selah”
‭‭Psalms‬ ‭52‬:‭1‬-‭5‬ ‭NKJV‬‬

“A soft answer turns away wrath, But a harsh word stirs up anger. The tongue of the wise uses knowledge rightly, But the mouth of fools pours forth foolishness. The eyes of the Lord are in every place, Keeping watch on the evil and the good. A wholesome tongue is a tree of life, But perverseness in it breaks the spirit. A fool despises his father’s instruction, But he who receives correction is prudent.”
‭‭Proverbs‬ ‭15‬:‭1‬-‭5‬ ‭NKJV‬‬
