"Sivan" is the name of the third month of the Hebrew calendar. The twenty-third day is near the middle of June on Western calendars. (See: [[rc://en/ta/man/translate/translate-hebrewmonths]] and [[rc://en/ta/man/translate/translate-ordinal]] and [[rc://en/ta/man/translate/translate-names]])
A "province" is a large area into which some countries are divided for the purposes of government. See how you translated this in in [Esther 1:1](../01/01.md).
