Study Bible

The tongue of the wise commends knowledge
This phrase emphasizes the value of wisdom in communication. In biblical context, wisdom is often associated with the fear of the Lord (Proverbs 9:10) and is considered a divine gift. The wise person uses their speech to promote understanding and truth, reflecting the biblical principle that words have the power to build up or tear down (Proverbs 18:21). The Hebrew culture placed a high value on oral tradition and the spoken word, which was a primary means of teaching and preserving knowledge. This aligns with the New Testament teaching in James 3:13, where wisdom is demonstrated through good conduct and humility. The wise tongue is a type of Christ, who is described as the Word made flesh (John 1:14), embodying perfect wisdom and truth.

but the mouth of the fool spouts folly
In contrast, this phrase highlights the destructive nature of foolish speech. In the biblical context, a fool is not merely someone lacking intelligence but is often characterized by moral and spiritual deficiency, rejecting God's wisdom (Psalm 14:1). The fool's speech is reckless and devoid of understanding, leading to chaos and harm. This is consistent with the cultural understanding of folly in ancient Israel, where speech was a reflection of one's character and relationship with God. The imagery of "spouting" suggests an uncontrolled and excessive outpouring, akin to a fountain that cannot be stopped, which is echoed in James 3:5-6, where the tongue is described as a small part of the body that can cause great destruction. This serves as a warning against careless words and aligns with the broader biblical narrative that emphasizes the importance of self-control and discernment in speech.
