'Happened' in the Bible

These are the words of Nehemiah son of Hacaliah: It so happened that in the month of Kislev, in the twentieth year, I was in Susa the citadel.

So it happened that the Jews who were living near them came and warned us repeatedly about all the schemes they were plotting against us.

It so happened that when our adversaries heard that we were aware of these matters, God frustrated their intentions. Then all of us returned to the wall, each to his own work.

So Ezra the priest brought the law before the assembly which included men and women and all those able to understand what they heard. (This happened on the first day of the seventh month.)

You are righteous with regard to all that has happened to us, for you have acted faithfully. It is we who have been in the wrong!
