John Gill Commentary 1 Chronicles 22:4

"and cedar-trees without number: for the Sidonians and they of Tyre brought cedar-trees in abundance to David." — 1 Chronicles 22:4 (ASV)

Also cedar trees in abundance
To be sawed into boards and planks for the ceiling, wainscotting, and flooring of the temple, and other things:

for the Zidonians, and they of Tyre, brought much cedar wood to David ;
from Mount Lebanon, which was chiefly in their possession; and which they did either of themselves as a free gift and present to him, or at his request, for which he paid them; and this is another thing prefiguring the help of the Gentiles in building up the church of Christ in Gospel times.
