 In the Book of Esther, servants of the harem of Ahasuerus such as Hegai and Shashgaz as well as other servants such as Hatach, Harbonah, Bigthan, and Teresh are referred to as "sarisim".Being exposed to the consorts of the king, they would likely have been castrated.There is some confusion regarding eunuchs in Old Testament passages, since the Hebrew word for eunuch, "saris" (סריס), could also refer to other servants and officials who had not been castrated but served in similar capacities.
