Cyril of Alexandria : And it is written also in Exodus that when the ruler of the land of the Egyptians with his warriors was pursuing after the Israelites and was already upon the point of engaging with them in battle, the angel of God stood between the camp of the Israelites and of the Egyptians, and the one came not near the other all the night. There is therefore nothing unbefitting in supposing here also that the holy angel who was the guardian of the synagogue offered supplications in its behalf and prayed for a respite, if perchance yielding to better influence it might yet bring forth fruit. — HOMILIES ON THE GOSPEL OF Luke 96 Gregory of Nazianzus : Therefore this darkness of the body has been placed between us and God, like the cloud of old between the Egyptians and the Hebrews. This is perhaps what is meant by "He made darkness his separate place," namely, our dullness, through which few can see even a little. — THEOLOGICAL ORATION 2:12
