'Happened' in the Bible

So [the] Philistines were afraid, for they said, "God has come to the camp." And they said, "Woe to us, {for this has never happened before!}

And the man said to Eli, "I am the [one] who has come from the battle line! I have fled today from the battle line!" And he said, "{What exactly happened}, my son?"

You must watch; if it goes up by the way of its territory to Beth Shemesh, he has caused this great disaster to [come on] us. But if not, then we will know his hand has not struck us; it [was by] chance [that] this happened to us.

{And when} all who knew him {formerly} saw that he prophesied with prophets, the people said to one another, "What [is] this [that] has happened to the son of Kish? [Is] Saul also among the prophets?"

{And the} next day Saul placed the people [in] three divisions. Then they came into the middle of the camp {at the early morning watch} and struck down {the Ammonites} until the heat of the day. It happened that the remainder were scattered {so that no two among them remained together}.

But Saul said nothing on that day, for he thought, "{Something happened to him}. He [is] not [ceremonially] clean; surely he [is] not clean."
