Yehoshua ben Perachyah and Nittai of Arbel received [the Mesorah] from them.  Yehoshua ben Perachyah says: Make a teacher for yourself, purchase a friend for yourself, and judge every person favorably.

Nittai of Arbel says: Distance [yourself] from a bad neighbor, do not associate with a wicked person, and do not disregard [the possibility] of retribution.
