Proverbs 27:12-22

12 The clever see danger and hide; but the simple go on, and suffer for it.
13 Take the garment of one who has given surety for a stranger; seize the pledge given as surety for foreigners.
14 Whoever blesses a neighbor with a loud voice, rising early in the morning, will be counted as cursing.
15 A continual dripping on a rainy day and a contentious wife are alike;
16 to restrain her is to restrain the wind or to grasp oil in the right hand.
17 Iron sharpens iron, and one person sharpens the wits of another.
18 Anyone who tends a fig tree will eat its fruit, and anyone who takes care of a master will be honored.
19 Just as water reflects the face, so one human heart reflects another.
20 Sheol and Abaddon are never satisfied, and human eyes are never satisfied.
21 The crucible is for silver, and the furnace is for gold, so a person is tested by being praised.
22 Crush a fool in a mortar with a pestle along with crushed grain, but the folly will not be driven out.
