1 Chronicles 22:3-5

3David also provided great quantities of iron for nails for the doors of the gates and for clamps, aas well as bronze in quantities beyond weighing, 4and cedar timbers without number, bfor the Sidonians and Tyrians brought great quantities of cedar to David. 5For David said, cSolomon my son is young and inexperienced, and the house that is to be built for the Lord must be exceedingly magnificent, of fame and glory throughout all lands. I will therefore make preparation for it.” So David provided materials in great quantity before his death.

1 Chronicles 22:14-16

14With great pains I have provided for the house of the Lord d100,000 talents
A  talent was about 75 pounds or 34 kilograms
of gold, a million talents of silver, and fbronze and iron beyond weighing, for there is so much of it; timber and stone, too, I have provided. To these you must add.
15You have an abundance of workmen: stonecutters, masons, carpenters, and all kinds of craftsmen without number, skilled in working 16gold, silver, bronze, and iron. Arise and work! gThe Lord be with you!”
