2 Chronicles 4:18

Thus Solomon made all these vessels in great abundance: for the weight of the brass could not be found out.

Solomon provided temple furnishings on a lavish scale, multiplying the vessels until their number was very great. Because of that abundance, no reckoning of the total weight of the bronze used in them was arrived at. The casting of these vessels was carried out in the plain of the Jordan. There the work was done in clayey soil, in the district lying between Succoth and Zeredathah.
