13. There are four characters among men: he who says, "What is mine is mine and what is thine is thine," his is a neutral character; some say, "This is a character like that of Sodom"; he who says, "What is mine is thine and what is thine is mine," is a boor; he who says, "What is mine is thine and what is thine is thine," is a saint; he who says, "What is thine is mine and what is mine is mine," is a wicked man. 14. There are four kinds of tempers: he whom it is easy to provoke and easy to pacify, his loss disappears in his gain; he whom it is hard to provoke and hard to pacify, his gain disappears in his loss; he whom it is hard to provoke and easy to pacify is a saint; he whom it is easy to provoke and hard to pacify is a wicked man. 15. There are four qualities in disciples: he who quickly understands and quickly forgets, his gain disappears in his loss; he who understands with difficulty and forgets with difficulty, his loss disappears in his gain; he who understands quickly and forgets with difficulty, his is a good portion; he who understands with difficulty and forgets quickly, his is an evil portion. 16. As to almsgiving there are four dispositions: he who desires to give, but that others should not give, his eye is evil toward what appertains to others; he who desires that others should give, but will not give himself, his eye is evil against what is his own; he who gives and wishes others to give is a saint; he who will not give and does not wish others to give is a wicked man. 17. There are four characters among those who attend the house of study: he who goes and does not practise secures the reward for going; he who practises but does not go secures the reward for practising; he who goes and practises is a saint; he who neither goes nor practises is a wicked man. 18. There are four qualities among those that sit before the wise: they are like a sponge, a funnel, a strainer, or a sieve: a sponge, which sucks up everything; a funnel, which lets in at one end and out at the other; a strainer, which lets the wine pass out and retains the dregs; a sieve, which lets out the bran and retains the fine flour. 19. Whenever love depends upon some material cause, with the passing away of that cause, the love, too, passes away; but if it be not depending upon such a cause, it will not pass away for ever. Which love was that which depended upon a material cause? Such was the love of Ammon and Tamar. And that which depended upon no such cause? Such was the love of David and Jonathan. 20. Every controversy that is in the Name of Heaven shall in the end lead to a permanent result, but every controversy that is not in the Name of Heaven shall not lead to a permanent result. Which controversy was that which was in the Name of Heaven? Such was the controversy of Hillel and Shammai. And that which was not in the Name of Heaven? Such was the controversy of Korah and all his company.
