'Sparks' in the Bible

Yet man is born unto trouble, as the sparks fly upward.

Out of his mouth go burning lamps, and sparks of fire leap out.

As one pretending to be feeble, Who is casting sparks, arrows, and death,

Behold, all ye that kindle a fire, that compass yourselves about with sparks: walk in the light of your fire, and in the sparks that ye have kindled. This shall ye have of mine hand; ye shall lie down in sorrow.

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.
