A volunteer sifting ancient debris from the vicinity of the Temple Mount uncovered a small stone with the word beka—a measurement of weight equal to a half-shekel—inscribed on it in Hebrew. In First Temple times, such stones were used in scales to weigh precious metals. Amanda Borschel-Dan writes:
The beka [was] used by pilgrims paying their half-shekel tax before ascending to the Temple Mount. . . . The word beka appears twice in the Torah: first as the weight of gold in a nose ring given to the matriarch Rebecca in the book of Genesis, and later in the book of Exodus as a weight for the donation brought by the Jewish people for the maintenance of the Temple and the census, as recorded in Exodus 38:26. . . .
The beka stone was discovered in dirt taken from 2013 excavations under Robinson’s Arch. According to Eli Shukron, [the director of the excavation], the earth came from a drainage canal under the foundation of the Western Wall.
During this era, unlike several hundred years later, there was no half-shekel coin. Pilgrims brought the equivalent weight, a beka, in silver to pay their tax, which would have been measured out on scales in the very spot under the Temple Mount where the tiny stone weight was unearthed.
