Divrey Hayamim Alef 22:3-5

Orthodox Jewish Bible

³ And Dovid prepared barzel (iron) in abundance for the masmerim (nails) for the daletot (doors) of the she’arim, and for the joints; and nechoshet unweighable in abundance;

⁴ Also cedar timber in abundance, for the Tzidonim and the Tzorim brought much cedar lumber to Dovid.

⁵ And Dovid said, Sh’lomo beni (my son) is na’ar and tender, and the Bayit that is to be built for Hashem must be exceeding magnificent, of fame and of tiferet before all nations. I will therefore now make preparation for it. So Dovid prepared abundantly before his mot (death).
