"Actions speak louder than words." "Birds of a feather flock together." "Love is blind." While most people are familiar with these phrases, very few know that they all have a common source - the Talmud. In Jewish tradition, the Talmud embodies the laws of Judaism, as well as a way of intellectual development. It first evolved to interpret the Old Testament, but in time its range of concerns grew to include astronomy, diet, travel and more.
