Sivan in the Bible

Then the king's scribes were called at that time in the third month, the month Sivan, on the twenty-third of it. And it was written according to all that Mordecai commanded to the Jews, and to the lieutenants and the governors and rulers of the provinces from India to Ethiopia, a hundred and twenty-seven provinces, to every province according to the writing of it, and to every people in their writing, and to the Jews according to their writing and according to their language.
