In Proverbs 10:8, the wise heed commandments while fools babble and come to ruin — a close parallel to the storing knowledge vs ruinous speech contrast here.

Proverbs 1:5 reinforces the theme: a wise man hears and increases learning — exactly the 'laying up knowledge' of the wise.

Proverbs 9:9 similarly teaches that giving instruction to a wise man makes him yet wiser — consistent with storing knowledge.

In Proverbs 13:3, guarding the mouth preserves life, while open lips bring ruin — directly paralleling the fool's mouth bringing ruin here.

Proverbs 19:8 says getting wisdom loves one's soul — consistent with the value of storing knowledge.

In Proverbs 21:23, watching mouth and tongue keeps one out of trouble — the positive counterpart to the fool's ruin here.

Matthew 12:35 uses the same treasure metaphor: a good man brings good from his heart's treasure, paralleling the wise storing knowledge.

Matthew 13:52 depicts a scribe bringing out treasures new and old — directly mirrors the wise laying up knowledge and producing it.

In 1 Kings 12:10, Rehoboam's young advisors give arrogant advice — a narrative example of foolish speech that leads to ruin, as warned here.

Ecclesiastes 10:12 mirrors the proverb: the wise speak graciously, but fools are destroyed by their own lips.
