Exodus 13:17 - 13:18
Pillars of Cloud and Fire
17 Now it happened that when Pharaoh had let the people go, God did not guide them by the way of the land of the Philistines, even though it was near; for God said, “Lest the people change their minds when they see war, and return to Egypt.” 18 Hence God turned the people to the way of the wilderness to the Red Sea; and the sons of Israel went up in battle array from the land of Egypt.
