The war has never ended for the Jews. From the moment they were chosen, satan started to annihilate them. They didn’t ask to be chosen but kind of ended up that way without even a debate or a referendum. Of course, all this has to do with when Abram was called by God to start a nation that would be separated onto Him as an example to the world - Gen. 12. We first see them truly forming as a nation when Moses told Pharaoh to release them so that they could go away and practice as God wants them to. God’s appointed Moses strikes down an Egyptian which was a foretelling of God putting down and overwhelming Pharaoh's company resulting in the Exodus and of course end time prophecy. Now, when the people of Israel was chosen it was not based on their merit but simply because God was keeping His Word to Abraham and for His plans - Jos. 21:43-45.
