Collar may mean the neck opening or collar band of a robe. In other passages the word refers to pendants or drops used as ornaments, and it may also refer to shackles or an instrument of punishment.
The collar band appears in the description of a garment. “Collars” among the Midianite spoils are rendered “pendants,” while another related word is associated with shackles.
The term translated “collar” has several underlying Hebrew words with different senses, including drop, mouth or opening, and stocks or shackles.
