Charles Ellicott Commentary Isaiah 47:14

"Behold, they shall be as stubble; the fire shall burn them; they shall not deliver themselves from the power of the flame: it shall not be a coal to warm at, nor a fire to sit before." — Isaiah 47:14 (ASV)

There shall not be a coal to warm at. — Better, it shall not be ... The destroying flame shall be altogether different from the fire on the hearth, at which a man can sit and warm himself.
