Gefundenes Geld behalten: Ist es eine Sünde im Judentum?

Judaism has the most developed lost-property law in the ancient world — two chapters of Bava Metzia, in fact. The Torah command is hashavat aveidah, returning the lost (Deuteronomy 22:1-3), and the rabbis derived its limits precisely: you must pick up a lost object if the owner would want it back, announce it publicly, and care for it meanwhile (feed the animal, protect the garment). The famous marker test: an object with identifying signs (simanim) must be returned on proof, because the owner has not yet despaired (yi'ush); scattered coins with no signs may be kept once the owner has certainly despaired. Even then, the pious precedent (middat chasidut) is to go beyond the law. Maimonides rules that one who returns lost property fulfills a positive commandment, and one who ignores it transgresses two: 'you shall not ignore it' and 'you shall restore it.' The modern application runs through the same channels — a found phone has simanim by definition; a found envelope of cash outside a shop likely has an owner who will retrace steps. The tradition's teaching posture is that God pairs losers with finders deliberately.
