John Wesley on Exodus 14:10

They were sore afraid - They knew the strength of the enemy, and their own weakness; numerous indeed they were, but all foot, unarmed, undisciplined, dispirited, by long servitude, and now pent up, so that they could not escape. On one hand was Pi - hahiroth, a range of craggy rocks unpassable; on the other hand were Migdol and Baal - zephon, forts upon the frontiers of Egypt; before them was the sea, behind them were the Egyptians; so that there was no way open for them but upwards, and thence their deliverance came.
