"And it came to pass in the morning watch, that Jehovah looked forth upon the host of the Egyptians through the pillar of fire and of cloud, and discomfited the host of the Egyptians." — Exodus 14:24 (ASV)

In the morning watch - At sunrise, a little before 6 a.m. in April.

Troubled - By a sudden panic.
