Ben Bag Bag says: Delve into it and delve into it, for everything is [contained] in it. And with it you will see, and grow old and wizened with it, and do not stir from it, for you can have no better portion than it.
Avot5: 23
בֶּן הֵא הֵא אוֹמֵר: לְפוּם צַעֲרָא אַגְרָא.
Ben Hei Hei says: The reward is commen-surate with the exertion.
