Sirach 34:10 CPDV

⁸  The word of the law will be fulfilled without a lie, and wisdom will be made plain in the mouths of the faithful.

⁹  He who has not been tested, what does he know? A man with much experience will consider many things. And whoever has learned much will explain with understanding.

¹⁰  He who has no experience knows little. And he who has done many things has made many mistakes.

¹¹  He who has not been tested, what kind of things can he know? He who has been deceived will be more cunning.

¹²  I have seen much by wandering, and the customs of many things.
