10. There are four sorts of men: He who says, that which is mine is mine, and that which is thine is thine, is a passable custom, and some say this was the custom of Sodom. He who says, what is thine is mine, and what is mine is thine, is the custom of the ignorant. He who says, what is mine is thine, and what is thine is also thine, is the custom of the pious. He who says, what is mine is mine, and what is thine is mine, is the custom of the wicked.
11. There are four sorts of passionate men: He who is easily provoked and easily pacified loses more than he gains; he whom it is difficult to provoke and difficult to pacify gains more than he loses; he whom it is difficult to provoke and easy to pacify is pious; but he who is easily provoked and with difficulty pacified is wicked.
12. There are four sorts of disciples: He who is quick to hear and quick to forget loses more than he gains; he who is slow to hear and slow to forget gains more than he loses; he who is quick to hear and slow to forget is wise; he who is slow to hear and quick to forget has an evil portion.
13. There are four sorts in those who bestow charity: He who is willing to give but does not wish that others should give, has an envious eye toward others; he who likes to see others give but will not give, has an evil eye toward himself; he who is willing to give and that others should also give, acts piously; he who will not give and likes not that others should give, acts wickedly.
14. There are four sorts in those who go to college: He who goes but does not study, has only the reward of going; he who studies and does not go, has the reward of action; he who goes and studies, is pious; he who neither goes nor studies, is wicked.
15. There are four sorts in those who sit before the Sages: Those who act as a sponge, a funnel, a strainer, and a sieve; as a sponge which sucks up all, as a funnel which receives at one end and lets out at the other, as a strainer which lets the wine pass through, but retains the lees, and as a sieve which lets the bran pass through but retains the fine flour.
16. Every affection that depends on some carnal cause, if that cause ceases the affection ceases, but that which does not depend on such a cause will never cease. Where do we meet with an affection dependent on a carnal cause? Such was the love of Ammon to Tamar; but that which does not depend on such a cause was the love of David and Jonathan.
