Planting Trees

Planting Trees

A rabbi was once passing through a field where he saw a very old man planting an oak
tree. “Why are you planting the oak tree,” he asked. “Surely you do not expect to live
long enough to see the acorn grow into a tree?”
The old man replied: “My ancestors planted trees not for themselves, but for us, in order
that we might enjoy their shade or their fruit. I am doing likewise for those who come
after me.”
