Talmud su Proverbi 22:1

If you make yourself a surety [for another] it should be with the object of paying [that surety];¹²If called upon to do so. or if you become a guarantor it should be with the object of paying [the guarantee].¹³Therefore do not offer to become a guarantor lightheartedly. If you borrow [money] it should be with the object of repaying [the loan];¹⁴So borrow only if you are in a position to repay. and if you lend money bear in mind that you may have to claim it¹⁵And have difficulty in collecting it. and that you might [even] have to make a settlement.¹⁶And lose part of the sum loaned. Another reading is lehafsid, ‘lose the sum’.
If one has acquired for himself a good name,¹⁷Cf. Prov. 22, 1; Eccl. 7, 1; Aboth II, 8 (Sonc. ed., II, 7, p. 17). he has acquired it for himself.¹⁸In the sense that, unlike any other possession, it cannot be transmitted to another. If one has acquired for himself words of Torah, he has acquired for himself the life of the World to Come.
