Sirach 21:16

¹⁴The inner parts of a fool are like a broken vessel, and he will hold no knowledge as long as he liveth.

¹⁵If a skilful man hear a wise word, he will commend it, and add unto it: but as soon as one of no understanding heareth it, it displeaseth him, and he casteth it behind his back.

— Sirach 21:16 —

¹⁷They enquire at the mouth of the wise man in the congregation, and they shall ponder his words in their heart.

¹⁸As is a house that is destroyed, so is wisdom to a fool: and the knowledge of the unwise is as talk without sense.
