Daniel 3:19-21

Then Nebuchadnezzar was furious with Shadrach, Meshach and Abednego, and his attitude toward them changed. He ordered the furnace heated seven times hotter than usual²⁰ and commanded some of the strongest soldiers in his army to tie up Shadrach, Meshach and Abednego and throw them into the blazing furnace. ²¹ So these men, wearing their robes, trousers, turbans and other clothes, were bound and thrown into the blazing furnace.
