Tur HaArokh
ויקח משה את אשתו ואת בניו, “he took his wife and his sons, etc.” This verse is similar to Numbers 26,8 ובני פלוא אליאב, “and the sons of Phalu were Eliav. Even though Phalu is reported as having had only the one son, the Torah uses the plural mode ובני, when referring to this. Similarly, here. At this time Moses had only one son, Gershom. Tzippporah who had been pregnant with Eliezer at that time gave birth to him on the way, as becomes clear in verse 24 of our chapter. It is possible that before G’d had spoken to Moses at Mount Chorev, Tzipporah had born Gershom, and that she had again become pregnant. When Moses returned to Yitro from the desert Eliezer had just been born. Seeing that Moses was anxious to be on his way, he had not yet circumcised his new born son, so that his mother had not yet named the baby. She did not name him right after she had circumcised him, being not yet sure whether Moses would survive his encounter with the angel who had tried to harm him. It was only after Moses arrived safely in Egypt and realized that he had indeed been saved from all those who had wanted to kill him, that he named the baby with a name which reflected his gratitude to G’d for having saved him from all this.
