'Happened' in the Bible

The Philistines were afraid, for they said, “God has come into the camp.” And they said, “Woe [disaster is coming] to us! For nothing like this has happened before.

But watch, if it goes up by the way of its own territory to Beth-shemesh, then [you will know that] He has done us this great evil. But if not, then we will know that it was not His hand that struck us; this disaster happened to us by chance.”
