1. Chronik 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.

"Out of the eater comes forth meat." It was upon occasion of the terrible judgment inflicted on Israel for the sin of David that God gave intimation of the setting up of another altar, and of the place where he would have the temple to be built, upon which David was excited with great vigour to make preparation for that great work, wherein, though he had long since designed it, it should seem, he had, of late, grown remiss, till awakened by the alarm of that judgment. The tokens of God's favour he received after those of his displeasure, I. Directed him to the place (Ch1 22:1). II. Encouraged and quickened him to the work. 1. He set himself to prepare for the building (Ch1 22:2-5). 2. He instructed Solomon, and gave him a charge concerning this work (Ch1 22:6-16). 3. He commanded the princes to assist him in it (Ch1 22:17-19). There is a great deal of difference between the frame of David's spirit in the beginning of the former chapter and in the beginning of this. There, in the pride of his heart, he was numbering the people; here, in his humility, preparing for the service of God. There corruption was uppermost (but the well of living water in the soul, though it may be muddied, will work itself clear again); grace here has recovered the upper hand.
