15 Sand, salt, and a lump of iron are easier to bear than an unintelligent person.

Sirach 22:15 In-Context

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.
