Damascus has become feeble (Isaiah 17)

Isaiah chapter 17 is another short chapter with few notes. Really, the only thing of substance noted there is the supposed failed prophecy of verse one, but I think the SAB is overstating what the prophecy is really saying. It doesn't say Damascus will be destroyed, and it doesn't say it will no longer be inhabited, it just says it will be left in ruins. I think it's likely that when the Babylonians defeated the Assyrians, Damascus was seriously damaged, but clearly it was rebuilt, and there's nothing against the prophecy in that fact. The prophecy also talks about a fortress in Ephraim being destroyed, but I don't know if that's an Israelite fortress or an Assyrian one; probably the latter. The rest of the chapter talks about people forsaking idols and turning to worship the God of Israel, and I assume this is talking about Israelites, but it's possible even Assyrians are turned from their gods.
