1 Chronicles 22:3, 14

David supplied a large amount of iron to be used for making nails and hinges for the gate doors. He also supplied more bronze than could be weighed

“Solomon, I have worked hard getting many of the materials for building the Temple of the LORD. I have supplied about seven and one-half million pounds of gold, about seventy-five million pounds of silver, so much bronze and iron it cannot be weighed, and wood and stone. You may add to them.
