Jeremiah 15:12
Shall iron break the northern iron and the steel?
Shall iron break the northern iron and the steel? Can iron break iron, especially that which comes from the north, which was harder than the common iron; or steel, the hardest of all? though the Jews were hard as iron, they could not prevail against and overcome Jeremiah, who was made an iron pillar and brasen walls against them, Jeremiah 1:18, and so these words are spoken for his comfort and encouragement: or they may respect the Jews and the Chaldeans; and the sense be, that the Jews, as mighty and as strong as they fancied themselves to be, and boasted that they were, they could not find themselves a match for the Chaldean army, which came out of the north; and may be said to be as hard as the northern iron, which came from the Chalybes, a people in the north, near Pontus, from whom steel has its name in the Latin tongue; and this sense agrees with what follows.
