'Burning Coals' in the Bible

"And then he shall take a censer full of burning coals out of the altar that is before the LORD, and his handful of sweet cense beaten small, and bring them within the veil,

Even mighty and sharp arrows, with hot burning coals.

Let hot burning coals fall upon them; let them be cast into the fire, and into the pit, that they never rise up again.

And the similitude of the beasts and the fashion of them was as burning coals of fire and as fire brands, walking between the beasts. And the fire did shine, and out of the fire proceeded lightning.
