And he will cut down the thickets of the forest with iron, and Lebanon shall fall by a mighty one.

I will go before thee, and make the rough places smooth. I will break in pieces the doors of brass, and cut apart the bars of iron.

Because I knew that thou are obstinate, and thy neck is an iron sinew, and thy brow brass,

For brass I will bring gold, and for iron I will bring silver, and for wood brass, and for stones iron. I will also make thy officers peace, and thine overseers righteousness.
