12
Mourn for the dead for seven days, but mourn for the foolish and the ungodly all the days of their lives.
13
Don't talk a lot with fools, and don't go to the unintelligent. Be on guard against them so that you don't have trouble and don't get dirty when they shake themselves off. Stay away from them and you will find rest, and their senselessness won't make you weary.
14
What's heavier than lead? And what name does it have but "Fool"?
15
Sand, salt, and a lump of iron are easier to bear than an unintelligent person.
16
A wooden beam fastened into a building won't be loosened by an earthquake. So a heart firmly set on thoughtful counsel won't be afraid at any time.
17
A heart fixed on thoughtful understanding is like an engraved ornament on a smooth wall.
18
A protective barrier set on a high place will never endure against the wind. So a timid heart backed up by a fool's plan will never endure against any fear.
Preserving friendship
19 Whoever pricks an eye will make tears flow, and whoever pricks a heart reveals its feelings.
20
Whoever throws a stone at birds scares them off, and whoever insults a friend breaks up a friendship.
21
If you draw a sword on a friend, don't despair, because there can be a way back.
22
If you speak harshly to a friend, don't be concerned, because there can be reconciliation. But in the case of reproach, arrogance, the revealing of a secret, or a treacherous blow, any friend will flee.
