Rabbi Rahumai said: From your words we could conclude that the needs of this world were created before the heavens. He answered yes. What does this resemble? A king wanted to plant a tree in his garden. He searched the entire garden to find a spring flowing with water that would nourish the tree, but could not find any. He then said, "I will dig for water, and will bring forth a spring to nourish the tree." He dug and opened a well, flowing with living water. He then planted the tree, and it stood, giving forth fruit. It was successfully rooted, since it was always watered from the well.
