Moshe's Son(s)

According to J, Moshe had one son, Gershom (see Shemot 2:22). According to E, he had two sons, Gershom and Eliezer (see Shemot 18:4). It says in Shemot 4:20 that Moshe took his wife and sons, plural. As this is from J, it likely originally said son, instead of sons, and it was RJE who made this small change, which is even smaller in Hebrew, בָּנָיו, rather than בָּנָו.
