Therefore, the Master saith:
Whosoever bends his back over the study of our books, devoting his leisure thereto, is not occupied with vain thoughts, but fears God, and shall reign in the Kingdom without fail until he die.
For what ye seek is not of small price. Woe unto you who seek the very great and compensating treasure of God!
Know ye not that for the smallest purpose in the world, earthly men will give themselves to death, and what, therefore, ought they to do for this most excellent and almost impossible offering?
