Proverbs 7:3-5 (ESV)
3 Bind them on your fingers;
write them on the tablet of your heart.
4 Say to wisdom, “You are my sister,”
and call insight your intimate friend,
5 to keep you from the forbidden woman,
from the adulteress with her smooth words.
The father continues to exhort his son to take his instruction seriously. He has already urged him to keep and treasure his commandments. Now he adds another vivid image. “Bind them on your fingers.” The language echoes Deuteronomy 6:6-8, where God’s people are told to keep his words close and visible, even as a sign on the hand. The point is clear. Whatever the son does, his actions are to be guided by the teaching of the Lord. Every decision and every step should be filtered through God’s wisdom.
The father then adds, “Write them on the tablet of your heart.” Wisdom is not meant to remain external. It is to become an internal guide. The son is called to memorize the commands of his father and keep them constantly before him. As he continues to practice them, this instruction becomes part of his character. Over time the teaching is no longer merely remembered. It is written on his heart.
The father also calls his son to develop a close relationship with wisdom. “Say to wisdom, ‘You are my sister,’ and call insight your intimate friend.” These are terms of affection and loyalty. Wisdom is to be treated like a beloved family member or trusted companion. True spiritual success requires this kind of closeness. Song of Solomon 4:9-10 uses similar language to describe deep affection and attachment. Intimacy with wisdom will keep you from intimacy with sin.
Wisdom protects. The father explains that it will keep the son “from the forbidden woman, from the adulteress with her smooth words.” Temptation often arrives through flattery and seductive speech. Frequently the appeal is not merely physical but aimed at pride. Words that stroke the ego can be more powerful than the allure of beauty itself. Our own vanity can become a trap. Yet these flattering promises are nothing but lies when compared with the truth of God’s word.
Once again the father reminds his son that his teaching guards him from sexual sin. Proverbs speaks often about forbidden relationships because the danger is real and the consequences are severe. The question for us is simple. How do we view the commands of the Lord? Do we see them as burdens, or do we cherish them like a trusted friend or beloved family member? Those who love God’s word will find that it protects them and leads them into life.
