'Morning watch' in the Bible

And it came to pass in the morning watch, that Jehovah looked upon the camp of the Egyptians, in the pillar of fire and of the cloud, and embarrassed the camp of the Egyptians.

And it came to pass the next day that Saul set the people in three companies; and they came into the midst of the camp in the morning watch, and smote Ammon until the heat of the day: and it came to pass that they who remained were scattered, and not two of them were left together.
