דברי הימים ב, פרק ד׳, פסוק י״ז

Creating the massive copper vessels for the Temple was a monumental task that required specific geological and topographical conditions. Consequently, the work took place in a specialized location within the Jordan Valley. The chosen site was a flat plain [מצודת ציון]. The sheer size of the Temple vessels made it impossible to use standard casting molds. To solve this challenge, the craftsmen employed a unique method: they dug the exact shapes of the vessels directly into the earth and poured the molten copper into these natural molds [מצודת דוד, רד ק]. This specific region was selected because its ground consisted of a thick, dense clay or red earth, making it exceptionally well-suited for metal casting [רש י, רד ק].

The casting occurred in the area between Sukkot and Zeredathah. However, the parallel historical account in the Book of Kings refers to this location as Zarethan. The primary approach among commentators is that the location simply had two names [מצודת ציון], or that the two names share a clear linguistic connection [רד ק, רלב ג]. Another perspective suggests a historical evolution, explaining that the name of the place naturally changed over the years by the time the Book of Chronicles was recorded [מלבי ם]. Alternatively, a symbolic interpretation connects the name Zeredathah to Jeroboam son of Nebat, who originated from the city of Zeredah. In this view, the name serves as a subtle hint that in the future, Jeroboam would rise to power and actively restrict and diminish the religion of God [רש י].
