'Three' in the Bible

Go, get together all the Jews who are present in Shushan, and go without food for me, taking no food or drink night or day for three days: and I and my women will do the same; and so I will go in to the king, which is against the law: and if death is to be my fate, then let it come.

For the Jews who were in Shushan came together again on the fourteenth day of the month Adar and put to death three hundred men in Shushan; but they put not a hand on their goods.
