Charles Ellicott Commentary Isaiah 9:10

"The bricks are fallen, but we will build with hewn stone; the sycomores are cut down, but we will put cedars in their place." — Isaiah 9:10 (ASV)

The bricks are fallen down ... —Sun-dried bricks and the cheap timber of the sycamore (1 Kings 10:27) were the common materials used for the dwellings of the poor, hewn stones and cedar for the palaces of the rich. Whatever injury Samaria had sustained (the words are too proverbially figurative to make a literal interpretation probable), through the intervention of Tiglath-pileser, was, its rulers thought, merely the prelude to a great and more lasting victory even than that of 2 Chronicles 28:6.
