1 Chronicles 22:3, 14

David prepared large quantities of iron to make nails for the doors of the gates and for the clamps (trusses), and more bronze than could be weighed

Now listen, with great trouble I have prepared and provided for the house of the LORD 100,000 talents of gold, 1,000,000 talents of silver, and bronze and iron beyond weighing, for they are great in quantity. I have also prepared and provided timber and stone, and you may add to them.
