Adam Clarke on Joshua 10:41

And all the country of Goshen - Calmet contends that this was the very same country in which the Hebrews dwelt before their departure from Egypt; and according to this hypothesis he has constructed his map, causing it to extend from the Nile, which was called the river of Egypt, along the frontiers of the land of Cush or Arabia. It however appears plain that there was a city named Goshen in the tribe of Judah, see Jos 15:51; and this probably gave name to the adjacent country which may be that referred to above.
