To understand the reasons why the Jews protected the men at the expense of their daughters, one has to understand Jewish belief about how and why the Messiah would come.
The “Holiness Code” in Leviticus 17-22 was a list of commands which the Jews thought made them holy in God’s eyes. Jewish belief was that adherance to the law of Moses, primarily laid out in the holiness code in Leviticus, was one of the things that would directly contribute to the coming of the Messiah. If Israelites were holy according to the Mosaic law, the messiah would come. If Israel was not holy according to the Mosaic law, the messiah was prevented from coming. Through the Davidic kingdom and into the time of Jesus, belief that personal holiness would directly contribute to the coming of the messiah, and that violations of the holiness code were actually preventing the comming of the Messiah, was so strong that the Book of Leviticus was used to teach children how to read and write. Children would go off to the yeshiva schools at a very early age and would learn their ABC’s and how to read and write from Leviticus. This served the dual purpose of literacy and teaching children how to be holy according to God’s law.
The holiness code of the Mosaic law and its implications for the coming of the Messiah was so strong that it led later to the rise of the strictest Jewish sect, the Pharisees, of which Saul (Paul) was one. A devout Jew would go to astonishing lengths not to violate the holiness code and thereby contribute to the prevention of the coming of the Messiah.
You shall not lie with a male as with a woman; such a thing is an abomination. (Leviticus 18:22)
Sex between men was specifically prohibited in the holiness code. A devout Jew looking for the coming of the Messiah simply would not violate this law and would probably do anything to prevent others from violating it. To my knowledge, giving of a daughter was not prohibited.
So the actions of those who protected the men from homosexual rape at the expense of their very daughters, while abhorrent to our modern eyes, was actually the action of a devout Jew who loved God. His zeal for the coming of the Messiah would have caused him to sacrifice his very daughter for the sake of God’s kingdom. And this was Paul’s reason for persecuting the early Church as well. Paul viewed the Christians who violated the mosaic law as actually preventing the coming of the Messiah and so his persecution of the Church was due to his zeal for God and desire for the Messiah. Of course he didn’t realize that the Messiah had already come. When viewed in light of jewish belief about the holiness code and its implications of the coming of the Messiah, one has to actually admire Paul’s zeal, if not his judgement.
The Jews who gave their daughters over to rape and death for love of God and the coming of the Messiah would have been viewed as righteous. And when viewed through the lense of ancient Judaism, we see how things have changed very little. The Catholic martyrs give testimonly to how we are called to do the same as those devout Jews. We are called to give our very lives rather than disavow God’s authority and sovereignty. The more things change, the more they stay the same.
