New Century Version
9 It is better to live in a corner on the roof[a]
than inside the house with a quarreling wife.
10 Evil people only want to harm others.
Their neighbors get no mercy from them.
11 If you punish those who make fun of wisdom, a foolish person may gain some wisdom.
But if you teach the wise, they will get knowledge.
- 21:9 roof In Bible times houses were built with flat roofs. The roof was used for drying things such as flax and fruit. And it was used as an extra room, as a place for worship, and as a cool place to sleep in the summer.
