In Exodus 14:2, this signifies the beginning of a state for undergoing temptations. (Arcana Coelestia 8130)

8130. 'And encamp before Pi Hahiroth, between Migdol and the sea, before Baal Zephon' means the beginning of the state for undergoing temptations. This is clear from the meaning of 'encamping' as the arrangement of truth and good, dealt with in 4236, 8103(end), in this case for undergoing temptations. This is the state that is meant by the places at which they were to encamp. The fact that this state is meant is evident from what followed next: Pharaoh with his army subsequently pitched his camp there, and at the sight of them the children of Israel were subjected to a feeling of great anxiety, by which an initial state of temptations is meant. See what follows at verses 9-12.
