A pillar of fire was one of the manifestations of the presence of the God of Israel in the Torah, the five books ascribed to Moses which conventionally appear at the beginning of the Christian Bible's Old Testament and the Jewish Tanakh. According to Exodus, the pillar of fire provided light so that the Israelites could travel by night during the Exodus from Egypt. Scripture traditionally pairs a pillar of fire with the manifestation of the divine presence by day as the pillar of cloud. The combination meant that the Children of Israel "could travel by day or night". Throughout the Israelite's time in the desert, traveling from Egypt to Canaan, YHWH continually used this pillar of fire and cloud to lead his people and to remind them of his presence. When the pillar of God moved forward, the people of Israel would pack up their camp and follow behind it. Similarly, when the pillar of God's presence stopped, the Israelites would set up camp underneath it. The Levites would set up the Tabernacle of the Lord directly underneath the cloud of the Lord. This way, God's presence was visibly in the center of the camp at all times.
