Matthew Henry on 1 Chronicles 22:1-5
Here is, I. The place fixed for the building of the temple (Ch1 22:1): Then David said, by inspiration of God, and as a declaration of his mind, This is the house of the Lord God. If a temple must be built for God, it is fit that it be left to him to choose the ground, for all the earth is his; and this is the ground he makes choice of - ground that pertained to a Jebusite, and perhaps there was not a spot of ground besides, in or about Jerusalem, that did so - a happy presage of the setting up of the gospel temple among the Gentiles.

Irons - for the nails, etc. - Iron for bolts, bars, hinges, etc., etc.
John Gill on 1 Chronicles 22:3
And David prepared iron in abundance for the nails for the doors of the gates, and for the joinings,.... Great plenty of iron to make nails of for joining the boards together, of which the doors and gates were to be made, and for the fastening of the hinges of them:
and brass in abundance without weight; for making the altar of brass, and the laver of brass, and other vessels. Brass was much used by the Heathens in sacred things, as Macrobius (p) observes.
