Exodus 13:17-18

Now when Pharaoh had let the people go, God did not lead them by the way of the land of the Philistines, even though it was near; for God said, “The people might change their minds when they see war, and return to Egypt.” Hence God led the people around by the way of the wilderness to the Red Sea; and the sons of Israel went up in martial array from the land of Egypt.
