Proverbs 27:15-22

A quarrelsome wife is like the dripping of a leaky roof in a rainstorm; restraining her is like restraining the wind or grasping oil with the hand. As iron sharpens iron, so one person sharpens another. The one who guards a fig tree will eat its fruit, and whoever protects their master will be honored. As water reflects the face, so one’s life reflects the heart. Death and Destruction are never satisfied, and neither are human eyes. The crucible for silver and the furnace for gold, but people are tested by their praise. Though you grind a fool in a mortar, grinding them like grain with a pestle, you will not remove their folly from them.
