Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abednego: therefore he spake, and commanded that they should heat the furnace one seven times more than it was wont to be heated. Then was Nebuchadnezzar full of fury - How strange is this, after having had so many proofs of the supremacy of Jehovah! He had seen how God poured contempt upon his authority in the case of the three Hebrews, and yet he will try his strength once more! How infatuated is man!
Seven times more - As hot as it could be made. Seven expresses the great intensity of the heat.
