Correct version of pasuk about wisdom

Question

An old teacher of mine is about to turn 90 and I'm trying to locate a pasuk, which, I think, says: "Treasure the words of a wise man for they are..." or "Heed the words of a wise man, for they are more [valuable?] than [treasure?]". I'm beginning to wonder whether I've confused one or more pesukim. Any ideas?

Answer 1

Perhaps Mishlei 25:12:

יב נֶזֶם זָהָב, וַחֲלִי-כָתֶם-- מוֹכִיחַ חָכָם, עַל-אֹזֶן שֹׁמָעַת.
12 As an ear-ring of gold, and an ornament of fine gold, so is a wise reprover upon an obedient ear.

In other words, the rebuke of a wise man is gold to those who will accept it.

Answer 2

This smacks of Mishlei thematically. Perhaps you're thinking of 22:17-18, in terms of wisdom being quid pro quo, although there is no treasure here:

הַט אָזְנְךָ וּשְׁמַע דִּבְרֵי חֲכָמִים וְלִבְּךָ תָּשִׁית לְדַעְתִּי. כִּי נָעִים כִּי תִשְׁמְרֵם בְּבִטְנֶךָ יִכֹּנוּ יַחְדָּו עַל שְׂפָתֶיךָ

JPS:

Incline thine ear, and hear the words of the wise, and apply thy heart unto my knowledge. For it is a pleasant thing if thou keep them within thee; let them be established altogether upon thy lips.

Answer 3

Perhaps you were thinking of the first half of Ecclesiastes 10:12:

דִּבְרֵי פִי-חָכָם, חֵן; וְשִׂפְתוֹת כְּסִיל, תְּבַלְּעֶנּוּ.‏
The words of a wise man's mouth are gracious; but the lips of a fool will swallow up himself.
