'Firmly' in the Bible

Bound firmly with ropes, these three men Shadrach, Meshach, and Abednego fell into the blazing fire furnace.

Astonished, King Nebuchadnezzar stood up in terror, and asked his advisors, "Didn't we throw three men into the fire, bound firmly with ropes?" In reply they told the king, "Yes, your majesty."

I'll inform you about what has been recorded in the Book of Truth. No one stands firmly with me against these opponents, except Michael your prince.
