'Sparks' in the Bible

“For man is born for trouble,[As naturally] as sparks fly upward.

“Out of his mouth go burning torches,And sparks of fire leap out.

Listen carefully, all you who kindle your own fire [devising your own man-made plan of salvation],Who surround yourselves with torches,Walk by the light of your [self-made] fireAnd among the torches that you have set ablaze.But this you will have from My hand:You will lie down in [a place of] torment.

Because the king’s command was urgent and the furnace was extremely hot, the flame of the fire killed the men who carried up Shadrach, Meshach, and Abed-nego.
