1 Kings 7:44-47
English Standard Version
45Now the pots, the shovels, and the basins, all these vessels in the house of the Lord, which Hiram made for King Solomon, were of burnished bronze.
46In the plain of the Jordan the king cast them, in the clay ground between Succoth and Zarethan.
47And Solomon left all the vessels unweighed, because there were so many of them; the weight of the bronze was not ascertained.
