Definition: "Ucdla" in the Bible refers to a special type of garment worn by women during certain periods (specifically, during menstruation). It was made of wool or silk and consisted of a large collar that extended over one's shoulders. During the time period mentioned, it was commonly used for religious observances as well as ceremonial purposes. The word "ucdla" is found in the Old Testament at Judges 16:25, where it appears to be a personal item worn by a woman and refers to the attire she wore during her menstrual cycle.
