And it came to pass, that in the morning watch the Lord looked unto the host of the Egyptians through the pillar of fire and of the cloud, and troubled the host of the Egyptians, (Exodus 14:24)
The “morning watch” of the Hebrews lasted from about 3 A.M. until sunrise, which, at this time of the year, would occur about 5:45.
The Lord looked.
In Ps. 77:17-19 a description of what happened at this point is given. A sudden cloudburst was accompanied by lightning and thunder. Pressing forward on the bed of the Red Sea, whose heaped-up waters they could now see on either side, the Egyptians must have been terrified (see also Josephus Antiquities ii. 16. 3).
