Maybe he means Isaiah 17 was partially fulfilled?
Here is Jack Kelley's take on Isaiah 17......
The Slow Motion Fulfillment Of Isaiah 17
“
See, Damascus will no longer be a city but will become a heap of ruins. The cities of Aroer will be deserted and left to flocks, which will lie down, with no one to make them afraid” (
Isaiah 17:1-2).
Isaiah 17 is an oracle concerning Damascus that was partially fulfilled when the Assyrians conquered Aram in 732 BC and 10 years later conquered the breakaway Northern Kingdom of Israel.
It’s the portion of
Isaiah 17 that were not fulfilled that concern us today, and the most obvious one is the fact that Damascus has never been reduced to a heap of ruins. Although the city has been conquered several times it has yet to be destroyed like the prophecy of
Isaiah 17:1-2 requires.
Damascus has proved to be a most resilient city. It was conquered by the Israelites (1000 BC), the Assyrians (732 BC), the Babylonians (606 BC), the Persians (530 BC), the Greeks (330 BC), the Nabateans (85 BC), the Romans (63 BC), the Byzantines (634 AD), the Mamelukes (1250 AD) and the Ottoman Turks (1516 AD). But the city itself has always survived and is now claimed to be the oldest continuously inhabited city in the world with a 5,000 year history. Its current population is close to 2 million, yet
Isaiah 17:1-2 indicates that it will one day cease to exist.
