Gaebelein's Annotated Bible
In that day the LORD with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea.CHAPTER 27 Israel’s Enemies Overthrown and the Great Restoration
1. Assyria, Babylon and Egypt punished (Isaiah 27:1) 2. What Jehovah has done and will do (Isaiah 27:2-11) 3. The vineyard established and the glorious consummation (Isaiah 27:12-13) This is a fitting finale to the second section of this book. Israel’s chief enemies are indicated by the leviathan, the serpent and the dragon. Behind them stands the serpent and the dragon, Satan. When these enemies are overthrown and Satan is bound then “Israel shall blossom and bud, and fill the face of the world with fruit.”
The last word tells of Israel’s literal regathering under the blowing of the trumpet Matthew 24:31 and their future worship in Jerusalem. The ending of the first and second sections are alike. They reveal Israel’s future glory and blessing.
