Verses 1–4
EXODUS - CHAPTER FOURTEEN
Verses 1-4:
God changed the direction of Israel’s march, from Southeast, to due south. Had they continued in their original course, they would have shortly come to the arid, treeless wastes east of the Bitter Lakes. Here they would have had little or no food for their flocks, and no water for themselves. To the south lay a well-watered district more suitable for their journey, though it was still within Egypt’s borders. To the east was the "sea," or the Red Sea.
The present sites of the cities mentioned are unknown. However, they were familiar to the writer of Exodus, and were important cities of that time.
Piha-hiroth is from a Semitic word meaning "entrance to the caves."
Migdol means "tower" or "fortified post," likely denoting a military post not far from the modern Suez.
Baal-zephon is a name of uncertain origin and meaning. Some scholars identify it as "Baal-Zebub," or "Baal-Sutech," personifying evil.
One cannot assume that only one or two days elapsed between the start of Israel’s journey and this present text. The logistics of moving such a huge number with all their goods and herds would require considerable time. It is likely that many days passed following the Passover, until Israel’s change of direction and present encampment.
The Lord informed Moses that Pharaoh would pursue Israel with the intent of returning the people to Egypt as slaves. This would give opportunity for a final demonstration of His power and glory.
