'Happened' in the Bible

The following events happened in the days of Ahasuerus. (I am referring to that Ahasuerus who used to rule over a hundred and twenty-seven provinces extending all the way from India to Ethiopia.)

Now there happened to be a Jewish man in Susa the citadel whose name was Mordecai. He was the son of Jair, the son of Shimei, the son of Kish, a Benjaminite,

It so happened that when the king's edict and his law became known many young women were taken to Susa the citadel to be placed under the authority of Hegai. Esther also was taken to the royal palace to be under the authority of Hegai, who was overseeing the women.

Then Mordecai related to him everything that had happened to him, even the specific amount of money that Haman had offered to pay to the king's treasuries for the Jews to be destroyed.

It so happened that on the third day Esther put on her royal attire and stood in the inner court of the palace, opposite the king's quarters. The king was sitting on his royal throne in the palace, opposite the entrance.

Haman then related to his wife Zeresh and to all his friends everything that had happened to him. These wise men, along with his wife Zeresh, said to him, "If indeed this Mordecai before whom you have begun to fall is Jewish, you will not prevail against him. No, you will surely fall before him!"

All of this happened on the thirteenth day of the month of Adar. They then rested on the fourteenth day and made it a day for banqueting and happiness.

Therefore, because of the account found in this letter and what they had faced in this regard and what had happened to them, the Jews established as binding on themselves, their descendants, and all who joined their company that they should observe these two days without fail, just as written and at the appropriate time on an annual basis.
