3. He who learns from his companion a single chapter, a single rule, a single verse, a single expression, or even a single letter, ought to pay him honor, for so we find with David, King of Israel, who learned only two things from Ahitophel (11), and yet regarded him as his master, his guide, and familiar friend, as it is said, "But it was thou, a man, mine equal, my guide, and my familiar friend" (12). Now, is it not an argument from minor to major (13), that if David, the King of Israel, who learned only two things from Ahitophel, regarded him as his master, guide, and familiar friend, he who learns from his fellow a chapter, rule, verse, expression, or even a single letter, is bound to pay him honor. And "honor" is nothing but _Torah_, as it is said, "The wise shall inherit honor (14) and the perfect shall inherit good" (15). And "good" is nothing but _Torah_, as it is said, "For I give you good doctrine, forsake ye not my _Torah_" (16). (11) Ahitophel deserted David to take up the cause of his rebellious son, Absalom. See II Sam. XVI, 15; XVII, 1 _et seq._ (12) See Ps. LV, 14. The two things David learned are hinted at in Ps. LV, 15. (13) See chapter I, n. 17. (14) Prov. III, 35. (15) _Ibid._, XXVIII, 10. (16) _Ibid._, IV, 2. 4. This is the way that is becoming for the study of the _Torah_: a morsel of bread with salt thou must eat (17), "and water by measure thou must drink" (18), thou must sleep upon the ground, and live a life of trouble the while thou toilest in the _Torah_. If thou doest thus, "Happy shalt thou be, and it shall be well with thee" (19), "happy shalt thou be" in this world, and "it shall be well with thee" in the world to come (20). (17) Even he who has only bread and salt to eat must busy himself with the study of the _Torah_. (18) Ezek. IV, 11. (19) Ps. CXXVIII, 2. (20) Cf. chapter IV, 1. 5. Seek not greatness for thyself, and court not honor; let thy works exceed thy learning; and crave not after the table of kings; for thy table is greater than theirs, and thy crown is greater than theirs, and thy Employer is faithful to pay thee the reward of thy work.
