'Burning Coals' in the Bible

Arrows of the strong one sharpened with burning coals of broom.

Burning coals shall be shaken upon them; he shall cast them into fire, into whirlpools; they shall not rise up.

If a man shall go upon burning coals shall his feet not be burnt?

As charcoal to burning coals and woods to fire, and a man of strifes to kindle strife.

And the likeness of the living creatures, their appearance as burning coals of fire, as the appearance of flames going about between the living creatures; and a shining to the fire, and from the fire will go forth lightning.
