Verses with the word coal in the Old Testament (4 verses):
2 Samuel 14:7
And, behold, the whole family is risen against thine handmaid, and they said, Deliver him that smote his brother, that we may kill him, for the life of his brother whom he slew; and we will destroy the heir also: and so they shall quench my coal which is left, and shall not leave to my husband neither name nor remainder upon the earth.
Then flew one of the seraphims unto me, having a live coal in his hand, 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.
Their visage is blacker than a coal; they are not known in the streets: their skin cleaveth to their bones; it is withered, it is become like a stick.
