Proverbs 15:2

The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.

The tongue of the wise useth knowledge aright - in the seasonable time, and proper place, and with due regard to the character of the hearers; all being adjusted to the balance of the sanctuary.

But the mouth of fools poureth out [ yabiya` (H5042 )] foolishness - babbleth it out at random, without choice or digested order, confusedly, copiously, with rapidity, and continuously, like a bubbling fountain.
