'Fire' in the Bible

I replied to the king, "O king, live forever! Why would I not appear dejected when the city with the graves of my ancestors lies desolate and its gates destroyed by fire?"

I proceeded through the Valley Gate by night, in the direction of the Well of the Dragons and the Dung Gate, inspecting the walls of Jerusalem that had been breached and its gates that had been destroyed by fire.

You guided them with a pillar of cloud by day and with a pillar of fire by night to illumine for them the path they were to travel.

"Due to your great compassion you did not abandon them in the desert. The pillar of cloud did not stop guiding them in the path by day, nor did the pillar of fire stop illuminating for them by night the path on which they should travel.
