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.

(p) Saturnal. l. 5. c. 19.
