KJV
Now when every maid’s turn was come to go
in to king Ahasuerus, after that she had been twelve months, according to the
manner of the women, (for so were the days of their purifications
accomplished, [to wit], six months with oil of myrrh, and six months with
sweet odours, and with [other] things for the purifying of the women;)
BSB
In the twelve months before her turn to go to King Xerxes, the harem regulation required each young woman to receive beauty treatments with oil of myrrh for six months, and then with perfumes and cosmetics for another six months.
