Ibn Ezra, on Isa 47:14

“Behold they are as stubble, fire hath burnt them, they shall not deliver themselves from the power of the dames: there are no coals wherewith they may be warmed, nor fire, that they may sit thereat.”

“Fire. The host of the enemy. Comp., There is a fire gone out of Heshbon (Num. 21:28). לחמם To warm at. It is infinitive of a verb (חמם) ע״ע, written in full, and similar in form to לשכב to lie (Gen. 34:7).—The meaning of the whole sentence is: they will perish and no remnant will be left of them.”
