Yes, very good provocative thought. Just as "tents of Shem" implies a school of teaching and not in the actual tent of one Shem, surely there was a tent of Moses
""tents of Shem" implies a school of teaching..."
Yes, and there are some who say that Abraham was "schooled" by Shem. Genealogies do not support the possibility of this, of course; just one reason why genealogies in the Bible are important. It puts things in chronological order, and puts the lie to spurious teachings. Understanding such as yours in explaining "tents of Shem" are also helpful.
