1 Chronicles 22:3, 14

And David prepared iron in abundance for the nails for the doors of the gates, and for the couplings; and brass in abundance without weight

Now, behold, in my affliction I have prepared for the house of Jehovah a hundred thousand talents of gold, and a thousand thousand talents of silver, and of brass and iron without weight; for it is in abundance: timber also and stone have I prepared; and thou mayest add thereto.
