Absalom said to Ahithophel, “Give us your advice. What should we do?” Ahithophel answered, “Sleep with your father’s concubines whom he left to take care of the palace. Then all Israel will hear that you have made yourself obnoxious to your father, and the hands of everyone with you will be more resolute.” So they pitched a tent for Absalom on the roof, and he slept with his father’s concubines in the sight of all Israel. Now in those days the advice Ahithophel gave was like that of one who inquires of God. That was how both David and Absalom regarded all of Ahithophel’s advice. – 2 Samuel 16:20-23
So all in all, because David killed Uzziah in order to sleep with Bathsheba, Uzziah’s wife, God cursed David and had David’s son forcibly have sex with his concubines “in the sight of all Israel!” What does this say about Yahweh, the God of Judaism and Christianity?
