2 Samuel 13:1 - Joseph Benson’s Commentary on the Old and New Testaments

Absalom, the son of David, had a fair sister His sister by both father and mother. For they were both born of Maacah, the daughter of Talmai, king of Geshur. Now began another part of Nathan's prophecy, I will raise up evil against thee out of thine own house, to be awfully fulfilled On David; and the sad scene of domestic troubles to be opened which were to befall his family. And it is probable he had not been long returned to Jerusalem, from the taking of Rabbah, before they began to take place and multiply upon him.
