1. The nomenclature of Exodus.
This book is called Exodus, that is, departure,[1] by a certain ὁδὸν/way, because it begins with the liberation of the afflicted Israelite people and their exodus out of Egypt unto the promised land, and narrates the journey following the exodus, with the name taken from Exodus 12:41, in which Moses says, And it came to pass at the end of the four hundred and thirty years, on the selfsame day, all the hosts of Jehovah יָצְאוּ, went out, from the land of Egypt. The Hebrews denominate the book אלה שמות, Elleh Shimoth, these are the names, from the first words of the book.
[1] Latin: exitus.
