Provérbios 8:12 Midrash: Ein Yaakov (Glick Edition) & Midrash Tehillim

(Ib. b) R. Elazar says: "Whoever teaches his daughter the Torah is as if he were teaching her frivolity." How is it possible that by teaching her the Torah, he teaches her frivolity? Said R. Abahu: "R. Elazar's reason is based on the following passage (Pr. 8, 12): I, wisdom dwell with prudence; i.e., as soon as wisdom enters a man he becomes prudent." But how will the Rabbis explain, I, wisdom dwell with prudence? This is needed to support the view of R. Jose b. R. Chanina. For R. Jose b. R. Chanina quoted: "The words of the Torah will not endure with one unless he is ready to strip himself of all other things, as it is said, I, wisdom dwell with prudence." R. Jochanan said: "The words of the Torah will not endure with one unless he admits that he does not know anything by himself, as it is said (Job. 28, 12) But wisdom, where shall it be formed?"

The verse "In my heart I have hidden your word" means that if a person internalizes the Torah and has it in their heart, the evil inclination does not control them and cannot harm them. As it says in Proverbs 8:12, "I, wisdom, dwell with prudence." Where wisdom resides, the evil inclination does not reign. Similarly, in Psalm 37:31 it says, "The Torah of his God is in his heart; his steps will not falter." And as Moses says in Deuteronomy 11:18, "Therefore, impress these My words upon your heart and upon your soul." Therefore, it is said, "In my heart I have hidden your word."
