1 Chronicles 22:3-5

3He provided a large amount of iron to make nails for the doors of the gateways and for the fittings, and more bronze than could be weighed. 4He also provided more cedar logs than could be counted, for the Sidonians and Tyrians had brought large numbers of them to David. 5David said, “My son Solomon is young and inexperienced, and the house to be built for the Lord should be of great magnificence and fame and splendor in the sight of all the nations. Therefore I will make preparations for it.” So David made extensive preparations before his death.
