Do not speak to a fool
This phrase advises against engaging in dialogue with someone characterized as a "fool." In biblical terms, a fool is not merely someone lacking intelligence but rather someone who rejects wisdom and moral instruction. The Hebrew word for fool, "kesil," often refers to a person who is morally deficient and resistant to correction. This aligns with the broader biblical theme that true wisdom begins with the fear of the Lord (Proverbs 1:7). The cultural context of ancient Israel placed a high value on wisdom and understanding, often associating foolishness with spiritual and moral failure. Jesus, in the New Testament, also warns against casting pearls before swine (Matthew 7:6), which parallels this advice by suggesting that sacred truths should not be wasted on those who will not appreciate them.

for he will despise the wisdom of your words
The second part of the verse explains the rationale behind the initial command. A fool, as defined in the biblical context, is someone who not only lacks wisdom but actively scorns it. This reflects a heart attitude that is closed to instruction and correction. The historical context of Proverbs, attributed to Solomon, suggests a society where wisdom was highly esteemed, and the rejection of it was seen as a serious flaw. This rejection is not just a passive ignorance but an active disdain, which can be seen in other scriptures such as Proverbs 1:22, where fools delight in their mockery. The New Testament echoes this sentiment in 1 Corinthians 1:18, where the message of the cross is described as foolishness to those who are perishing. This highlights the spiritual blindness that prevents fools from recognizing the value of wisdom, which ultimately points to Christ, who is described as the wisdom of God (1 Corinthians 1:24).

1. Fool
In the context of Proverbs, a fool is someone who rejects wisdom and understanding, often characterized by a lack of moral and spiritual insight. The Hebrew word used here is (kesil), which implies someone who is obstinate and morally deficient.

2. Wisdom
This is a central theme in the book of Proverbs, representing divine insight and understanding that leads to righteous living. Wisdom is often personified and is seen as a guiding principle for a godly life.

3. Solomon
Traditionally attributed as the author of Proverbs, Solomon was known for his wisdom, which he received from God. His teachings often contrast the wise and the foolish.Discernment in Communication
As believers, we must exercise discernment in choosing when and with whom to share wisdom. Not everyone is receptive, and we should be mindful of the potential futility in speaking to those who are obstinately foolish.

Value of Wisdom
Wisdom is precious and should be shared with those who are open to receiving it. We should seek to cultivate relationships with those who value and seek understanding.

Guarding Our Words
Our words have power and should be used wisely. Engaging in fruitless discussions with those who scorn wisdom can lead to frustration and conflict.

Patience and Prayer
Instead of engaging in futile arguments, we should pray for those who are resistant to wisdom, asking God to open their hearts and minds.

Reflecting Christ’s Example
Jesus often chose when to speak and when to remain silent, demonstrating wisdom in His interactions. We should strive to follow His example in our own lives.Top 10 Lessons from Proverbs 23

Proverbs 23:9 says not to speak to a fool; does this conflict with the New Testament’s call to share truth with everyone?

What does Proverbs 1:7 mean by 'fools despise wisdom'?

Proverbs 9:6 urges abandoning foolishness to truly live. How can 'foolishness' be objectively defined or measured in a modern, evidence-based society?

What does the Bible say about God's wisdom?(9) Speak not in the ears of a fool.--Do not waste thy time in explaining matters to him.

A fool.--A dull, stupid person. (Comp. Proverbs 1:22.)

Verse 9. - Here is another case in which "sweet words" are lost. Speak not in the ears of a fool. This does not mean, as it would in our English phrase - whisper not to a fool; but do not take the trouble to try to make him understand, impart nothing to him. The "fool" here (kesil) is the dull, stolid, stupid man. who cannot be moved from his own narrow groove (see on Proverbs 1:22). It is a mere casting of pearls before swine (Matthew 7:6) to speak to such a man of high aims, righteous motives, self-sacrifice (comp. Proverbs 9:8). He will despise the wisdom of thy words. He cannot enter into the meaning of words of wisdom; he has no appetite for them, he cannot assimilate them; and in his self-satisfied dulness he feels for them nothing but contempt (Ecclus. 22:7, etc., "Whoso teacheth a fool is as one that glueth a potsherd together, and as he that waketh one from a sound sleep. He that telleth a tale to a fool speaketh to one in a slumber: whey he hath told his tale, he will say, What is the matter?")
