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

I will go before you, and make the crooked places straight: I will break in pieces the gates of bronze, and cut asunder the bars of iron:

Because I knew that you are obstinate, and your neck is an iron sinew, and your brow bronze;

For bronze I will bring gold, and for iron I will bring silver, and for wood bronze, and for stones iron: I will also make your officers peace, and your rulers righteousness.
