Jewish law is ambivalent about amulets.
The Talmud permits ceratin kinds of amulets in certain situations. Others, however, not only permitted amulets but sold their own. Amulets were common to most Jewish communities and in a few they are still in use today. Inscriptions on amulets typically consist of Biblical verses or letters and coded formulas invested with mystical significance. Designs and figures generally have more than a purely decorative purpose.
