Details point to a 1st millennium BCE date for the composition of the narrative: Ezion-Geber (one of the Stations of the Exodus), for example, dates to a period between the 8th and 6th centuries BCE with possible further occupation into the 4th century BCE,[40] and those place-names on the Exodus route which have been identified – Goshen, Pithom, Succoth, Ramesses and Kadesh Barnea – point to the geography of the 1st millennium BCE rather than the 2nd.[41] Similarly, Pharaoh's fear that the Israelites might ally themselves with foreign invaders seems unlikely in the context of the late 2nd millennium, when Canaan was part of an Egyptian empire and Egypt faced no enemies in that direction, but does make sense in a 1st millennium BCE context, when Egypt was considerably weaker and faced invasion first from the Achaemenid Empire and later from the Seleucid Empire.[42] The mention of the dromedary in Exodus 9:3 also suggests a later date – the widespread domestication of the camel as a herd animal is thought not to have taken place before the late 2nd millennium BCE, after the Israelites had already emerged in Canaan,[43] and they did not become widespread in Egypt until c. 200–100 BCE.[44]
