David provided large amounts of iron for the nails that would be needed for the doors in the gates and for the clamps, and he gave more bronze than could be weighed.
The weight of the bronze from the two pillars, the Sea with the twelve bronze oxen beneath it, and the water carts was too great to be measured. These things had been made for the Lord’s Temple in the days of King Solomon.
“ I have worked hard to provide materials for building the Temple of the Lord— nearly 4,000 tons of gold, 40,000 tons of silver, and so much iron and bronze that it cannot be weighed. I have also gathered timber and stone for the walls, though you may need to add more.
