3David provided a large quantity of iron to make the nails for the doors of the gateways and for the fittings, together with more bronze than could be weighed
4and more cedar logs than could be counted; for the Sidonians and Tyrians had brought a large quantity of cedar logs to David.
5And David said, “My son Solomon is young and inexperienced, and the house to be built for the LORD must be exceedingly magnificent — famous and glorious throughout all lands. Therefore I must make preparations for it.” So David made lavish preparations before his death.
