Deuteronomy 7:3-4 says the following:
Do not intermarry. Do not give your (the Israelite) daughter for his (the non Jew) son, do not take his (the non Jew) daughter for your (the Israelite) son, for he (the non Jew) will turn your (the Israelite) son away from following Me, and they (your son and his(the non Jew) daughter) will worship the gods of others.
In order to explain this passage, I've made a diagram and "kid like" explanation of what this passage means.
I would like feedback. Note: All names used in diagram are made up just for the example.
(Diagram Explanation: First, according to Deut. 7:3-4 the prohibtion is for the Israelite NOT to give his daughter to the Non Jew. So we see that Esther doesn't listen to her Israelite parents (and God), and goes to marry Joe . The second is for the Israelite to not take the Non Jews daughter for the Jewish mans son. So we see that Binyomin doesnt listen to his parents or God and takes Susan the non Jew to be his wife.)
Put this scenario to the diagram:
Ok, well this sucks because your Jewish daughter Esther goes off the derech and marries Joe, from the non-Jewish family. HaShem says "Don't give your daughter to his son" well, oops, you did! You just violated the negative commandment of intermarriage because your Jewish daughter married a non-Jew. Too bad for you, because now she's under Joe's control and now their children and his offspring will no longer be Jewish.
Oh great, now you're Jewish son Binyomin wants to marry Susan from the non Jewish family. Now you have to take her into your care and she will come into a Jewish family. But HaShem says ", and do not take his daughter for your son, for he will turn your son away from Me, and they will worship the gods of others." So Bob, Susan's non Jewish father, will sway your son Binyomin and his daughter Susan away from the one true God? HaShem DOESNT say that Bob will sway Esther and Joe away from the one true God, why is that?
Ah, well we see that when Esther marries the non Jew, Joe, there is no point in mentioning that Bob till turn Esther away from the one true God because according to HaShem, once Esther marries Joe, she is already turned away from God. This does NOT say anything about their children though. Will Esther and Joe's children be Jewish? Or not Jewish? Does it even answer this? We conclude that HaShem did NOT mention that Bob will sway Esther and Joe away from the one true God because Esther CHOSE to sway herself away from the one true God just by marrying Joe and defying the law of intermarriage.
When we look at Binyomin and Susan's law-breaking scenario though, Binyomin is already following the one true God, and takes Susan to be his wife. This gives Susan's father Bob a chance to sway Binyomin and Susan!! What will Elisheva and Mordechai do!?!? Oh no! HaShem SPECIFICALLY says NOT to take his daughter for your son BECAUSE HE, the almighty, is trying to safeguard Binyomin from letting Bob (Susan's father) sway them to worshipping false gods.
You see in Esther and Joe's situation, there is no help for them. Esther has already committed 2 crimes - 1. She will follow her husband and go towards his ways, worshipping other gods so there is no need for HaShem to say anything more than "do not intermarry" beacuse the next outcome is already happening. But there is still a chance for Binyomin and Susan, they may have committed a crime of intermarrying, but there is a chance that since Susan is marrying a Jew that she too will want to worship the One True God, but not if Bob has anything to do with it!!
So...where does Rashi get a grandchild from? I think Rashi was trying to use circular reasoning to cover up the fact that this statement was never to mean anything about the grandchildren!! Does this verse in the Torah even relate to matrilineal or patrilineal descent? So..where in the Torah does it state that Jewish descent comes from your mother? According to every Rabbi we've asked.. nowhere!!! Scary, isn't it? Even in the Talmud itself, the only place where it talks about matrilineal vs. patrilineal is Rashi's reasoning, which we've just proven wrong!!!! Wow.. so this means that both the Torah, AND the Talmud both have no valid statement about whether the Jewish lineage is passed through the mother. This leaves only one more option... Jewish lineage according to the REST of the Torah (excluding the Deuteronomy 7:3-4 statement) is passed through the father!! "to your offspring I give this land" "our forefathers" (not our "foremothers") etc.!!!! Do you know that this means that all Jewish roots are lost, and the only people who truly know they are Jews to this day are the Kohanim and Levim because they are the only ones who have traced their Jewish lineage through their fathers!!! WOW.
Just to be sure we were translating the verse correctly according to the Hebrew, we tricked a non-religious Israeli into reading ONLY Deut. 7:3-4 and translating to the best of their knowledge what "ki yaseer et beencha" means, and he verified that it DEFINITELY does not talk about the grandchildren like Rashi points it. The only thing Deut. 7:3-4 states is that its a negative commandement against intermarriage and nothing more.
This just in:
