EST 2:12

12 Now before the turn of every na'arah came to go in to HaMelech Achashverosh, she had to complete the yemei merukeihen (the days of her [bodily] rubbings) which were prescribed for the nashim and which involved shneym asar chodesh [(twelve months)], shisha chodashim [(six months)] of shemen [(oil)] of myrrh and shisha chodashim [(six months)] of perfumes and beauty treatments for nashim.
