Wouldn't it have had to be immaculate conception if the following is true?
A scene at Karnak shows Rameses II in triumph supervising the castration of his captives. By the side, heaps of genitals that have been cut off are piled up. Isaiah, speaking prophetically for Yehouah, promises this fate to the offspring of Hezekiah the king:
And of thy sons that shall issue from thee, which thou shalt beget, shall they take away, and they shall be eunuchs in the palace of the king of Babylon. Isaiah 39:7
If this prophecy was fulfilled, then Jesus could not have been in the princely line of David, and if not, Isaiah was a false prophet. Castration of enemies is described nastily in the romance of Saul and David too:
And Saul said, Thus shall ye say to David, The king desireth not any dowry, but an hundred foreskins of the Philistines, to be avenged of the king’s enemies. But Saul thought to make David fall by the hand of the Philistines. And when his servants told David these words, it pleased David well to be the king’s son in law: and the days were not expired. Wherefore David arose and went, he and his men, and slew of the Philistines two hundred men, and David brought their foreskins, and they gave them in full tale to the king, that he might be the king’s son in law. And Saul gave him Michal his daughter to wife. 1 Samuel 18:25
Perhaps mentioning the castration as bringing foreskins softens the horror of it for Christians and Jews who think it is just some sort of obligatory circumcision. The Philistines were killed and their genitals were brought back as proof of the deed and as vulgar trophies
I haven't tracked down the geneology to determine if these assumptions are correct. Maybe someone else knows.
