Do you not see that rain falls from the sky and flows as springs and rivers in the earth; from which becomes crops of varying colors; then they dry and you see them turned yellow; then they become scattered debris.

And have you seen the water that you drink? Is it you who brought it down from the clouds? It could have been made bitter, so why are you not grateful?

And not alike are the two seas. One is fresh and sweet, palatable for drinking, and one is salty and bitter. And from each you eat tender meat and extract ornaments which you wear, and you see the ships plowing through them that you might seek bounty; and perhaps you will be grateful.
