'Burning Coals' in the Bible

And he shall take a censer full of burning coals of fire from off the altar before the LORD, and his hands full of sweet incense beaten small, and bring it within the veil:

Let burning coals fall upon them: let them be cast into the fire; into deep pits, that they rise not up again.

As coals are to burning coals, and wood to fire; so is a contentious man to kindle strife.

As for the likeness of the living creatures, their appearance was like burning coals of fire, like the appearance of torches: they went back and forth among the living creatures; and the fire was bright, and out of the fire went forth lightning.
