The aggadah identifies Abishag as the Shunammite who gave hospitality to Elisha the prophet . It relates that she was not half as beautiful as Sarah (Sanh. 39b). The fact that David did not make Abishag his legal wife is explained as due to his refusal to exceed the traditional number of wives (18) allowed to a king (Sanh. 22a, and Rashi, ibid.). Solomon's action is also vindicated on the grounds that the request made by Adonijah to be permitted to marry Abishag (I Kings 2:13ff.) represented a true threat to Solomon's position, as it is only the king, and not a commoner, who is allowed to make use of the servants of the deceased king (Sanh. 22a).
