'Morning watch' in the Bible

So it happened at the early morning watch [before dawn], that the Lord looked down on the army of the Egyptians through the pillar of fire and cloud and put them in a state of confusion.

The next morning Saul put the men into three companies; and they entered the [Ammonites’] camp during the [darkness of the early] morning watch and killed the Ammonites until the heat of the day; and the survivors were scattered, and no two of them were left together.

But understand this: If the head of the house had known what time of the night the thief was coming, he would have been on the alert and would not have allowed his house to be broken into.
