What does Isaiah chapter 17 mean?
This chapter is another prophecy from the Lord regarding one of the nations which surrounded Israel. Here Isaiah focuses on an earlier time, as compared to events of the previous oracles. The prophecy transitions from Damascus and becomes about God's judgment and salvation of Israel.Syria, also known as Aram, is north and east of Israel. Damascus was, and remains, the capital of Syria. This important city had a long history of conflict with God's people over the generations (2 Kings 5:1). Isaiah begins bluntly by saying that the city will become a heap of ruins. He states that another group of cities further south will become completely deserted (Isaiah 17:1–2).
Then Isaiah adds that Ephraim will share in the doom of Damascus. Ephraim was another name for the nation of Israel comprised of the northern ten tribes of God's people. They had made an alliance with Syria to stand against the coming attacks of the Assyrians. This oracle was fulfilled in 732 BC when the Assyrians destroyed Damascus and much of Israel. This attack killed and eventually deported most of the population of both nations (Isaiah 17:3).
Isaiah writes that Israel will no longer be able to defend itself. In the same way, Damascus will cease to be a kingdom after being claimed by the Assyrians. The survivors left behind in Syria will have the same glory as the remnant of those left in Israel: virtually nothing at all. The formerly prosperous Israel will be brought so low that they will seem like a once healthy person wasting away with disease. The nation will be like the poor people who survive on the gleanings left behind as charity when the wheat and olives are harvested in Israel (Isaiah 17:4–6).
Finally, the feeble remnant of Israel will look to their Creator, the Lord God, instead of to idols. Understanding that their false gods did not save them, the humbled and broken in the land will turn back to the Holy One of Israel. They will stop using false altars, incense, and pagan fertility gods like Asherim. The strong cities of Israel and Syria will be as deserted as the high places of Canaanite worship once were when Israel first came to the land. When God's people first arrived, they wiped out these places of worship to false gods (Exodus 34:13–14). Israel, though, eventually turned and worshiped those same Canaanite gods (Judges 2:1–3). They forgot about the God of their salvation. They failed to remember Who was the source of their shelter (Isaiah 17:7–9).
Isaiah compares Israel's idolatry to someone who devotes himself to carefully planting and cultivating a stranger's vine to provide food for himself. He tends the vine all the way through to the blossom stage, but never gets a harvest. This is the same thing as worshiping false gods: there is no return aside from grief and pain (Isaiah 17:10–11).
The roaring of the approaching enemy nations is like a violent storm raging on the sea. It is terrifying, and all in its path know they need shelter. The Lord wants Israel to trust in Him as that shelter. He is the One who sends the nations running with a single rebuke. He becomes an even more terrifying storm, chasing away the enemies of His people like dust before a strong wind (Isaiah 17:12–14).
