Matthew Henry
From his Commentary on the Whole Bible. Henry comments on passages, not single verses — this entry covers Proverbs 16:23.
Solomon had commended eloquence, or the sweetness of the lips (Pro 16:21), and seemed to prefer it before wisdom; but here he corrects himself, as it were, and shows that unless there be a good treasure within to support the eloquence it is worth little. Wisdom in the heart is the main matter. 1. It is this that directs us in speaking, that teaches the mouth what to speak, and when, and how, so that what is spoken may be proper, and pertinent, and seasonable; otherwise, though the language be ever so fine, it had better be unsaid. 2. It is this that gives weight to what we speak and adds learning to it, strength of reason and force of argument, without which, let a thing be ever so well worded, it will be rejected, when it comes to be considered, as trifling. Quaint expressions please the ear, and humour the fancy, but it is learning in the lips that must convince the judgment, and sway that, to which wisdom in the heart is necessary.

2 surviving comments on this verse. Each one is dated, so this reads as a timeline rather than a list.
The fountain of life is the instruction of the possessor, etc. When he said, of the possessor, he did not add, what the possessor holds. What then do we think was meant to be understood, except perhaps the very instruction itself? so that the full meaning is: The fountain of life is the instruction of the one possessing that very instruction; which is openly said to mean that the preacher truly opens the ways of life to his listeners who practices what he preaches himself; who possesses in his steadfast heart the love of the word, by which he instructs others, and does not scatter it like seed retained only in memory, as if gathered in a bosom, on the ground. But the teaching of fools is foolishness, because even if they have learned to say some good things by the practice of instruction, they themselves, foolish at heart, despise the same good things they speak.
He who is wise in heart, etc. He who keeps the wisdom of the Catholic faith, which he learned, unblemished in his heart, deservedly receives the name of prudent; but he who knows also to preach the same wisdom learnedly and to defend it against heretics will receive greater rewards for greater labor.

Summary
Proverbs 16:23 profoundly articulates the intrinsic connection between a person's inner wisdom and their outward communication. It posits that a truly discerning and intelligent heart is the wellspring from which wise and instructive speech flows, thereby enriching the words spoken and imparting valuable insight to those who hear. This verse underscores the intentionality and discipline required for speech that is not merely articulate but also edifying and reflective of a deep, cultivated understanding.
Context
Literary Context
Proverbs 16:23 is situated within a larger collection of Solomon's proverbs (chapters 10-22), which often present antithetical or synonymous parallels to highlight the contrast between wisdom and folly, righteousness and wickedness. This particular verse falls within a section that frequently addresses the themes of speech, the tongue, and the heart's influence on one's destiny. It builds upon the idea that the Lord directs one's steps (Proverbs 16:9) and that the heart's intentions are weighed by God (Proverbs 16:2). The preceding verses often discuss the value of wisdom and its protective qualities, making this verse a natural progression that focuses on wisdom's practical manifestation in communication.
Historical & Cultural Context
Ancient Israelite society, like many ancient Near Eastern cultures, placed a high value on oral tradition and the spoken word. Wisdom literature, such as Proverbs, was a primary means of moral and ethical instruction, often passed down from elders to younger generations. The "heart" (Hebrew: lêb) in this context refers not merely to the seat of emotion but to the core of one's being—the intellect, will, conscience, and moral center. Thus, a "wise heart" implies a person whose entire inner being is aligned with divine wisdom and discernment. Speech was seen as a powerful tool, capable of building up or tearing down, and therefore, its proper use was a consistent theme in wisdom teachings (Proverbs 18:21).
Key Themes
This proverb is rich with several interconnected themes. Firstly, it emphasizes the centrality of the heart as the source of all outward expression, particularly speech. It suggests that true wisdom is an internal quality that profoundly shapes external behavior. Secondly, it highlights the purposeful nature of wise communication. The wise person's words are not accidental or impulsive but are "taught" and "added" with intention, implying a deliberate and disciplined approach to speaking. Thirdly, it underscores the edifying and instructive quality of wise speech. The "learning" (Hebrew: leqach) imparted by the wise is not just information but insight and doctrine that benefits the hearer, aligning with the broader purpose of the book of Proverbs.
Exposition and Analysis
Key Word Analysis
This term refers to the innermost being of a person, encompassing not only emotions but also intellect, will, and moral decision-making. In biblical thought, the heart is the control center of one's life, the source from which thoughts, intentions, and actions originate. A "wise heart" is therefore a mind and will that is discerning, understanding, and aligned with divine truth.
This adjective describes someone who possesses practical skill, intelligence, and discernment. It signifies not just intellectual knowledge but the ability to apply that knowledge effectively in life, leading to prudent and skillful action. When applied to the heart, it denotes an inner state of sound judgment and insight that governs one's entire being.
This noun refers to something received, specifically instruction, doctrine, or insightful teaching. It highlights the beneficial and edifying nature of the speech that flows from a wise heart. The words spoken are not empty rhetoric but convey valuable wisdom and understanding, contributing to the hearer's knowledge and discernment.
Verse Breakdown
"The heart of the wise teacheth his mouth"
This clause establishes the internal origin of wise speech. The "heart of the wise," representing the core of a discerning and intelligent person, acts as the instructor or guide for their "mouth." This implies that truly wise communication is not spontaneous or accidental but is a deliberate outflow of an inner state of wisdom, thought, and understanding. The mouth, as the organ of speech, is depicted as being under the disciplined tutelage of the heart.
"and addeth learning to his lips"
This second clause functions as a synonymous parallelism, reinforcing and expanding upon the first. "Addeth learning" suggests that the wise heart not only directs the mouth but also continuously enriches the content of what is spoken. The "lips," another metonymy for speech, are imbued with "learning," which refers to instruction, doctrine, or insightful teaching. This signifies that the words of the wise are not just prudent but are also edifying, instructive, and beneficial, imparting valuable knowledge and understanding to others.
Literary Devices
Proverbs 16:23 employs several literary devices to convey its profound message. Parallelism is central to its structure, specifically synonymous parallelism, where the second half of the verse ("and addeth learning to his lips") reiterates and amplifies the meaning of the first half ("The heart of the wise teacheth his mouth"). Both clauses emphasize the direct link between inner wisdom and outward speech. Metonymy is also evident, as "mouth" and "lips" stand in for the act of speaking or the words themselves, while "heart" represents the entire inner person—intellect, will, and emotions. This use of metonymy vividly illustrates that the quality of one's speech is a direct reflection of their internal character and cultivated wisdom. The verse also implicitly uses personification, as the "heart" is depicted as an active agent that "teaches" and "adds," giving it a dynamic role in shaping communication.
Theological and Thematic Connections
Proverbs 16:23 offers a profound theological insight into the nature of human communication, asserting that true wisdom in speech originates from a deeply cultivated inner life. This aligns with the broader biblical emphasis on the heart as the wellspring of all life's issues, including one's words and actions. It teaches that superficial eloquence is insufficient; genuine, edifying speech is a direct manifestation of a heart that has been disciplined, discerning, and filled with divine understanding. This principle underscores the importance of internal transformation as a prerequisite for external impact, particularly in the realm of communication.
Reflection and Application
Proverbs 16:23 is a timeless challenge to cultivate not just eloquent speech, but genuinely wise communication rooted in a discerning heart. In an age saturated with information and rapid-fire communication, this verse calls us to pause and consider the source of our words. It reminds us that our speech is a direct reflection of our inner world—our thoughts, values, and understanding. To "teach our mouth" and "add learning to our lips" requires intentional spiritual and intellectual discipline, a commitment to filling our hearts with truth, wisdom, and discernment. This means actively engaging with God's Word, seeking His wisdom through prayer, and allowing the Holy Spirit to transform our inner being. When our hearts are saturated with divine wisdom, our words will naturally become a source of instruction, encouragement, and insight for others, reflecting the character of Christ within us. This proverb encourages us to be conduits of grace and truth, using our words to build up, not tear down, and to impart genuine understanding rather than empty rhetoric.
Questions for Reflection
FAQ
What does "the heart of the wise teacheth his mouth" truly mean?
This phrase means that a person's inner wisdom, discernment, and understanding (their "heart") actively guides and instructs their speech (their "mouth"). It implies that wise words are not accidental or impulsive, but rather a deliberate and disciplined outflow of a cultivated inner life. The heart, in biblical terms, is the center of intellect, will, and emotion, so a "wise heart" is one that thinks prudently, makes sound judgments, and is rooted in truth. This inner wisdom then shapes and controls what is spoken, ensuring that the words are thoughtful, appropriate, and beneficial. It aligns with the principle found in Luke 6:45 that "out of the abundance of the heart his mouth speaks."
How does "addeth learning to his lips" relate to the first part of the verse?
The second part of the verse, "and addeth learning to his lips," functions as a synonymous parallelism, reinforcing and expanding on the first. It means that the wise heart not only instructs the mouth on how to speak but also enriches the content of what is spoken. "Learning" (Hebrew: leqach) refers to instruction, doctrine, or insightful teaching. So, the wise person's words are not just prudent but also convey valuable wisdom, understanding, and edification to others. It suggests that their speech is a continuous source of insight and beneficial instruction, always seeking to impart knowledge and discernment, as opposed to idle chatter or foolishness (Proverbs 15:2).
Christ-Centered Fulfillment
Proverbs 16:23 finds its ultimate and perfect fulfillment in the person and ministry of Jesus Christ. He is the embodiment of divine wisdom, the very Word made flesh (John 1:14). His heart, perfectly aligned with the Father's will, flawlessly "taught His mouth" and "added learning to His lips." Every word Jesus spoke—whether teaching the multitudes on the Mount, rebuking the Pharisees (Matthew 23), or comforting His disciples (John 14)—was saturated with unparalleled wisdom, grace, and truth. His speech was never impulsive or empty; it always conveyed profound "learning" and divine instruction, revealing the Father and bringing life to those who heard (John 6:63). As believers, we are called to have the mind of Christ (Philippians 2:5), allowing His wisdom to transform our hearts so that our words, too, may become a source of grace and truth, reflecting Him who is Wisdom incarnate (1 Corinthians 1:30).
