'Coal' in the Bible

And behold, the whole family is risen against thy bondmaid, and they say, Deliver him that smote his brother, that we may put him to death, for the life of his brother whom he killed; and we will destroy the heir also: so they will quench my coal which is left, and will not leave to my husband a name or remnant on the earth.

And one of the seraphim flew unto me, and he had in his hand a glowing coal, which he had taken with the tongs from off the altar;

Behold, they shall be as stubble, the fire shall burn them; they shall not deliver themselves from the power of the flame: there shall not be a coal to warm at, nor fire to sit before it.

Behold, it is I who have created the smith that bloweth in the fire of coal, and that bringeth forth an instrument for his work; and I have created the destroyer to ravage.
