The Golden Bell was a small bell that hung on the High Priest's robe which he wore when he entered the Holy of Holies inside the Temple in Jerusalem. Golden bells were not part of the garments of regular temple priests. They were made only for the garments of the High Priest. They are mentioned in the Torah in the Book of Exodus. G-d is said to have ordered the Hight Priests to hang the bells on the hem of their robes and they would ring when the High Priests entered the Holy of Holies.
