The young man did as he was advised, and gave the slave his freedom afterward. But ever after he was wont to exclaim: —. ^Wisdom resides with the aged, and understanding in length of days.". David, King of Israel, was once lying upon his couch and many thoughts were passing through his mind. " Of what use in this world is the spider? thought he; "it but increases the dust and dirt of the world, making places unsightly and causing great annoyance.8.

Then he thought of an insane man: —. " How unfortunate is such a being. I know that all things are ordained by God with reason and purpose, yet this is beyond my comprehension; why should men be born idiots, or grow insane. Then the mosquitoes annoyed him, and the king thought: —. " What can the mosquito be good for? why was it created in the world? It but disturbs our comfort, and the world profits not by its existence.".

Yet King David lived to discover that these very insects, and the very condition of life, the being of which he deplored, were ordained even to his own benefit.
