Charles Spurgeon Commentary 1 Chronicles 22:3-4

"And David prepared iron in abundance for the nails for the doors of the gates, and for the couplings; and brass in abundance without weight; and cedar-trees without number: for the Sidonians and they of Tyre brought cedar-trees in abundance to David." — 1 Chronicles 22:3-4 (ASV)

And David prepared iron in abundance for the nails for the doors of the gates, and for the joinings; and brass in abundance without weight; Also cedar trees in abundance: for the Zidonians and they of Tyre brought much cedar wood to David.

Here, again, was a kind of prophecy of what would happen in better days, when the poor Gentiles would be permitted to have a share in the building of the house of God. These Tyrians and Zidonians were among the worst of idolaters, and yet they were used in their due place and subservience to hew the trees and float them to the temple, as near as they could get by sea to Joppa.
