Now there are a series of oracles against the various countries around Israel and Judah. As usual, the word of Yahweh came to Ezekiel, the son of man. He was to set his face against the Ammonites and prophesy against them. Who are the Ammonites? In the biblical sense, they are the descendants of Ammon, the son of Lot from the incest incident with his daughter in Genesis, chapter 19. They seem to have been east of the Jordan and north of Moab, but south of Assyria. The country of Ammon existed from about the 10th century to the 4th century BCE in what would have been the Gad territory as outlined in Joshua, chapter 13. Today it is part of the country of Jordan. Jeremiah, chapter 49, had also spoken out against them. They along with the Moabites were the constant enemies of Judah and Israel. At some point, they became part of the Assyrian empire and eventually ceased to exist. They certainly were related to Canaan and spoke a Semitic language.
Once again, Yahweh came to Ezekiel, the son of man. This time, it was about the origins and symbolic history of Jerusalem. The context was a berating of Jerusalem and her abominations. Unlike most stories of Israel that talk about Abraham, Isaac, and Jacob or the Egyptian experience under Moses, this history of Jerusalem starts with the Canaanites. This has led many to believe that there may be some validity to this history. Of course, this is specifically aimed at the inhabitants of Jerusalem. They were Canaanites whose mother was a Hittite with their father an Amorite. The Amorites were an ancient Syrian tribe with a Semitic language that also lived in Canaan from about 1700 BCE. From a biblical perspective based on Genesis, chapter 10, they were the descendants of Canaan and Ham. Amorite and Canaanite were interchangeable. They were definitely there before the Moses-Joshua experience. The Hittites were another Canaanite group that seemed to be friendly in many of the Genesis stories.
This section seems to imply that Israelites had settled in 5 Egyptian cities. We know that they were in Alexandria after the 4th century BCE. Perhaps there were some settlements in the 6th century BCE during the time of the Exile. On other hand, some of these may have been Israelites who never left Egypt when Moses led the Exodus. 5 of these cities in Egypt were speaking Canaanite or a Semitic language, not the Egyptian language. They all swore allegiance to Yahweh. One of these cities was the City of Sun, probably a reference to Heliopolis, which is near present day Cairo.
