'Morning watch' in the Bible

It happened in the morning watch, that Yahweh looked out on the Egyptian army through the pillar of fire and of cloud, and confused the Egyptian army.

It was so on the next day, that Saul put the people in three companies; and they came into the midst of the camp in the morning watch, and struck the Ammonites until the heat of the day: and it happened, that those who remained were scattered, so that no two of them were left together.
