Gershom is a Hebrew name from the Old Testament, meaning 'stranger' or 'alien'. It was given to Moses's son by his Midianite wife Zipporah, reflecting their status as outsiders. Additionally, Gershom is one of the twelve tribes of Israel, named after Manasseh's firstborn son. Over time, variations like Gershon and Gerschon have emerged, but the core meaning remains unchanged.
