Pillars of fire and cloud

The pillar of fire (Hebrew: עמוד אש, romanized: ‘ammuḏ ’ēš) and pillar of cloud (Hebrew: עמוד ענן, romanized: ‘ammūḏ ‘ānān) are a dual theophany (manifestation of God) described in various places in the first five books of the Hebrew Bible. The pillars are said to have guided the Israelites through the desert during the Exodus from Egypt. The pillar of cloud provided a visible guide for the Israelites during the day, while the pillar of fire lit their way by night.
