'Fire' in the Bible

Then Jehovah rained upon Sodom and upon Gomorrah brimstone and fire from Jehovah out of heaven;

And Abraham took the wood of the burnt-offering, and laid it upon Isaac his son. And he took in his hand the fire and the knife. And they went both of them together.

And Isaac spake unto Abraham his father, and said, My father. And he said, Here am I, my son. And he said, Behold, the fire and the wood. But where is the lamb for a burnt-offering?
