3. He who learns from his companion one chapter, sentence, verse, or expression, ought to behave toward him with respect; for thus we find by David, King of Israel, who having learned only two things from Ahitophel, called him his teacher, guide, and acquaintance, as is said, “But it was thou, a man mine equal, my guide, and mine acquaintance.”(507) Hence it may be deduced that if David, King of Israel, who having learned only two things from Ahitophel, called him his “teacher, guide, and acquaintance,” how much more ought he who learns from his companion a single chapter, sentence, verse, or expression, to show him the utmost respect? And there is no glory but the knowledge of the law; as is said, “The wise shall inherit glory”;(508) and the perfect shall inherit the good; but nothing is really good but the law, as is said, “For I give you good doctrine, forsake ye not my law.”(509) 4. Thus is the law to be observed: Thou shalt eat bread and salt, and water by measure shalt thou drink; on the earth shalt thou sleep, and a life of trouble shalt thou live; and thou shalt labor in the study of the law. If thou doest thus, thou shalt be happy, and it shall be well with thee; thou shalt be happy in this world, and it shall be well with thee in the world to come. 5. Seek not grandeur for thyself, neither covet more honor than thy learning merits. Crave not after the tables of kings; for thy table is greater than their table, and thy crown is greater than their crown; and the Master who employs thee is faithful to pay thee the reward of thy labor.
