'Morning watch' in the Bible

And in the morning watch, the Lord, looking out on the armies of the Egyptians from the pillar of fire and cloud, sent trouble on the army of the Egyptians;

Now on the day after, Saul put the people into three bands, and in the morning watch they came to the tents of the Ammonites, and they went on attacking them till the heat of the day: and those who were not put to death were put to flight in every direction, so that no two of them were together.
