Talmud sobre II Samuel 20:3

One marries neither the king’s widow nor his divorcee, because they were secluded to the day of their death, living in widowhood⁷⁷2S. 20:3, speaking of David’s concubines with whom Absalom had slept in public.. Rebbi Jehudah bar Pazi in the name of Rebbi Joḥanan: This teaches⁷⁸He reads צְרוּרוֹת not as “bound” but “tied, braided”. that David had them braided and adorned, and brought them before himself every day and told his evil inclination, you desire something which is forbidden to you;⁷⁹Since the concubines were not legally his wives, Absalom sinned by raping them, but they remained permitted to David by rabbinic rules. It was voluntarily that David refrained from sleeping with them. by your life, I shall make you desire what is permitted to you. The rabbis of Caesarea said, they actually were forbidden to him. If a private person’s vessel used by a private person is forbidden for the king’s use⁸⁰Since the king is prohibited from marrying his childless brother’s widow, it follows that the only women permitted to a king are either virgins or widows and divorcees of kings., a fortiori the king is forbidden to use the king’s vessels which were used by a private person.
