The directors of the excavation on behalf of the Antiquities Authority, archaeologists Eli Shukron and Professor Ronny Reich of Haifa University, said after the finding, “The bell looked as if it was sewn on the garment worn by a man of high authority in Jerusalem at the end of the Second Temple period.
“The bell was exposed in the city’s main drainage channel of that period, between the layers of dirt that had been piled on the floor of the channel,” they continued. “This drainage channel was built and hewn west to the Western Wall of the Temple Mount and drained the rainfall in the different parts of the city, through the City of David and the Shiloah Pool to the Kidron valley.”
The excavation area, above the drain, is located in the main street of Jerusalem which rose from the Shiloah Pool in the City of David. In this street an interchange was built through which people entered the Temple Mount. The remains of this interchange are what is known today as Robinson’s Arch. Archaeologists believe that the eminent man walked the streets of Jerusalem in the area of Robinson’s Arch and lost the golden bell which fell off his outfit into the drain beneath the street.
Jewish sources say that the high priests who served in the Holy Temple in Jerusalem used to hang golden bells on the edges of their coats. The book of Exodus (Shemot), for example, contains a description of the coat of Aaron the high priest in which it is said that coat contains, “bells of gold.”
While it is unknown if the bell belonged to one of the high priests, archaeologists have not ruled out the possibility.
Well, maybe. On the one hand it is true that the only references to golden bells in the Hebrew Bible are to bells on the vestments of the high priest (Exodus 28:33-34; 39:25-26). On the other hand, first, the only other mention of bells (a different Hebrew word) refers to horses' trappings (Zechariah 14:20). Presumably, bells were used in many other contexts, so our sample of cultural allusions is limited. But, you say, what about golden bells? Well, second, Isaiah 3:16-18 refers to bangles that the rich women of Jerusalem wore on their ankles and which "tinkled" or made some king of bangle noise. These ladies clearly had lots of jewelry and finery (cf. also vv. 19-23), so it seems entirely likely that they sometimes wore bells as jewelry and that some of those bells might well have been made of gold. And we know that Second-Temple-era ladies in Jerusalem had very nice gold earrings. So this bell need not have come from "a man of high authority."
