The assimilation and subsequent loss of Jews has been a problem since the beginning of Jewish history. Many of us were taught--in kindergarten, no less--how Abraham and Sarah converted many to Judaism. This is the midrashic explanation of the verse we will read next week, “and the nefesh, souls they made in Charan” (the simple explanation is that nefesh refers to the wealth they had acquired). Yet these anonymous people or their children must have assimilated, as we never hear from them again.
"And Yitro, the priest of Midian, the father-in-law of Moshe, heard all that G-d did for Moshe and to Israel his people, that G-d had taken the Israel out of Egypt" (Shemot 18:1). Of course, Yitro was not the only one who heard all that G-d had done. Yet he was the only one who was listening; the only one who cared enough and was moved enough to actually do something. While others likely were impressed to hear that a slave nation took on the worlds superpower, such lasted the 30 seconds or so they spoke about it. They then moved on with their daily activities.
We tend to view Adam as a failure at life, unable to obey his only command from G-d. Noach was better, yet many see him as one who could have accomplished so much more than what he did. Only with the advent of Avraham do we have the person capable of bringing G-d’s message to mankind.
