12. Hillel and Shammai (29) received (the tradition) from them.
Hillel said, "Be of the disciples of Aaron, loving peace and pursuing
peace (30), loving mankind and drawing them night to the _Torah_"
(31). 13. He used to say, "A name made great is a name destroyed
(32); he who does not increase (his knowledge) decreases (it); and he
who does not study deserves to die; and he who makes a worldly use of
the crown (of the _Torah_) shall waste away." 14. He used to say, "If
I am not for myself, who will be for me? But if I care for myself
only, what am I? (33). And if not now, when?"

(29) Hillel and Shammai, the most renowned of the "pairs"
([zugot]), lived about 100 years before the destruction of the
Temple. Each was the founder of a school, _Bet Hillel_ and
_Bet Shammai_, being generally opposed to one another in the
interpretation of the _Torah_. Hillel was the embodiment of
humility, gentleness, and kindness; Shammai was irritable, and
lacked gentleness and patience. The former's most celebrated
saying is, "What is hateful to thee do not do unto thy fellow
man; this is the whole _Torah_, the rest is mere commentary."

(30) Psalm XXIV, 15: "Seek peace and pursue it."

(31) Draw men to the _Torah_ by good example, not by
endeavoring to make converts.
