Apostas esportivas: é pecado no judaísmo?

Judaism's gambling law developed in an argument that still matters. The Mishnah disqualifies a professional dice-player from serving as a judge or witness, and Rav Sheshet explains in Sanhedrin 24b: because the player does not expect to lose, his payment is not true consent — a theory of the invalid wager that predates modern addiction research by fifteen centuries. Maimonides goes further and classifies the gambler's winnings as a form of robbery, since the loser's consent was extracted through the game itself. Yet casual gambling has always existed in Jewish life — the Purim raffle is a beloved counterexample — so the halakhic picture is one of strong discouragement rather than blanket prohibition. Modern rabbis dealing with sports betting emphasize the practical indicators: money needed elsewhere, hidden accounts, neglected obligations, and the inability to stop. Where those appear, the conversation shifts from 'is it permitted?' to repair — teshuvah, restitution, and treatment for what has become a compulsive behavior.
