TSK · Deuteronomy 8:9

saying,“Take home great wealth, a lot of cattle, silver, gold, bronze, iron, and a lot of clothing. Divide up the goods captured from your enemies with your brothers.”

David supplied a large amount of iron for the nails of the doors of the gates and for braces, more bronze than could be weighed,

Iron is taken from the ground, and rock is poured out as copper.
