Here is a good question. Why aren't Moshe Rabeinu's children spoken about in the Torah? Did they go in his footsteps?
Now they certainly walked in his footsteps; not only his children, everybody else's children walked in the footsteps of Moshe Rabeinu. Zichru toras Moshe avdi asher tzivisi oso b'Chorev al kol Yisroel chukim umishpatim, the Jewish nation all walked in Moshe Rabeinu's footsteps, don't make any mistake about that.
We see here a very queer phenomenon. Moshe Rabeinu, the greatest man that ever lived, married outside of his people. Isn't that a queer phenomenon? Of course in those days before matan Torah, there was no such thing as intermarriage, everybody was bnei Noach, and at Har Sinai everyone became geirim, so it was really no problem. But still, Aaron married from the zera Avrohom, and so did others. How is it that Hakadosh Baruch Hu caused this to happen? Now this doesn't happen by accident, it was part of Hashem's plan, that the greatest man and the leader of our people, the one from whose hand we received the Torah – Toras Moshe – should marry outside of the family. It's a big problem!
It was Hashem's plan. Hashem did not want Moshe Rabeinu's children to take over any office. There shouldn't be the slightest form of nepotism, of patronage, of selfishness. Moshe Rabeinu was the perfect man, but a perfect man is also a man, and had he had sons of the stock of the original family of Avrohom, who knows what would've happened? He would have a negia, a personal interest. So Hakadosh Baruch Hu purified him, and Moshe Rabeinu knew that his children could not be leaders in the Am Hashem. They were all frum Jews, no question about that "... bnei Moshe rabu l'maleh rosh" it says in Divrei Hayomim. A very big family, but no conspicuous mention of them in the Torah; he named them and that's all.
Hakadosh Baruch Hu wanted Moshe to be the model of a purely devoted, unselfish leader, and therefore Moshe Rabeinu's children took no office, and they even gained no mention subsequently in the Torah. Moshe is pure; he did everything only for others and nothing for himself at all.
And that was the Yad Hashem that caused him to marry a Midyanis, just for the purpose that the greatness of this personality should not be tinged by the smallest amount of personal interest.
By the mouth of Hashem they encamped, and by the mouth of Hashem they journeyed. (Bamidbar 9:20)
This is a model for the largest part of Israel's history. Our nation in its journeys has had no permanent location, and "Hashem, You have been our dwelling" (Tehillim 90:1). Wherever Israel goes, they are housed in Hashem's protective embrace as long as they are mindful of Him. Whenever they dismantled the Mishkan in preparation for their journey, it was considered as "Dismantling for the purposes of rebuilding in the same place" (Shabbos 31B), because wherever they would be when they rebuilt the Mishkan they were in the same location as they had been when they dismantled it; namely, in the midst of Hashem's loving embrace.
From this statement that all locations of Israel are considered as the same place, we understand that Hashem's Presence dwelt in Jerusalem, Bavel, Spain, France, Germany, Poland, Russia and then in the Western Hemisphere, wherever His people encamped. To those that seek Hashem in this world, the place to find Him is among the habitations of loyal Jewry.
