'Two' in the Bible

In those days Mordecai [was] sitting at the gate of the king. Bigthana and Teresh, two of the king's eunuchs from the keepers of the threshold, became angry and they conspired {to assassinate} King Ahasuerus.

And the matter was investigated and found [to be so]; and the two of them were hanged on [the] gallows, and it was written in the scroll of the events of the days before the presence of the king.

And it was found written how Mordecai had reported concerning Bigthana and Teresh, two of the king's eunuchs from the keepers of the threshold who had conspired {to assassinate} King Ahasuerus.

the Jews established and adopted [it] for themselves and for their offspring, and for all who joined them. They did not neglect {to observe} these two days every year as it was written and appointed to them.
