SPRAVEDLIVÉ MÍRY, VÁHY A OBJEMY PODLE TANACHU A RABÍNSKÉ TRADICE.

In rabbinic tradition, measures, weights, and volumes are of great importance in many halachic matters. The rabbis had to establish and explain: What is the minimum amount of food one must eat in order to recite the blessing after a meal? What is the maximum amount of non-kosher food in a kosher food that will not make the food inedible? What is the minimum amount of unleavened bread that one should eat on the first two days of Passover? Why is a person unjust if he weighs inaccurately and even if he weighs accurately and gives nothing extra? How is it possible to punish a person for an act he has not yet committed (ie, before „unfair" weighing or measuring)? [ABSTRACT FROM AUTHOR]
