Bamidbar: who’s missing

In the Talmud, the book of Bamidbar (Numbers to the King James authors), is generally referred to Sefer Pikudim. Pikudim means something closer to “ the ones who count. It evokes the reading on Rosh Hashanah: Gd Pokad Sarah. The first chapter of Bamidbar counts the tribal armies of Israel and arrays them around the temple. Among the countings is the naming of the sons of Moshe and and Aaron, but Moshe’s sons are not mentioned. Even the childless, dead sons of Aaron are mentioned, but not Gershom and Eliezer.Perhaps they were too dwarfed by their father. Perhaps they were corrupted by their Midianite upbringing. or alienated by the people because they did not share the Egypt experience. One can speculate about their absence, but the hole is there. It demonstrates that there is some selection in the counting. Would I have counted, would my children have made the cut? Is it better to be an anonymous number?
