Sivan in the Bible

Then at that time, on the twenty-third day of the third month, which is the month Sivan, the king's scribes were sent for; and everything ordered by Mordecai was put in writing and sent to the Jews and the captains and the rulers and the chiefs of all the divisions of the kingdom from India to Ethiopia, a hundred and twenty-seven divisions, to every division in the writing commonly used there, and to every people in their language, and to the Jews in their writing and their language.
