The wise lay up knowledge, but the mouth of a fool brings ruin near.
Observe, 1. It is the wisdom of the wise that they treasure up a stock of useful knowledge, which will be their preservation: Wisdom is therefore found in their lips (Pro 10:13), because it is laid up in their hearts, out of which store, like the good householder, they bring things new and old.
Wise men lay up knowledge,.... Which they get by reading, prayer, meditation, hearing the word of God, and conversation with good men: this they lay up in their hearts, minds, and memories, that they may not forget it, and as a rich treasure they highly value it; that they may bring it forth at proper times, and on proper occasions, for the benefit of others...
lay up knowledge--that is, as treasures for good use. mouth . . . destruction--or, "as to the mouth," &c., destruction is near; they expose themselves to evil by prating.
