This is a very old battle between Jacob and Esau. Esau is Edom, Genesis 36. "Edom is in modern Jewry", The Jewish Encyclopedia. The modern day Jews are not, and have never been, God's Israel people. The bible defines the word sheep when used as a figure of speech for only Israel. Christ said "my sheep hear my voice and follow me". They have been mostly doing that for almost 2000 years. They take the gospel to the world while they formed Christian nations as prophecy said they would. The words Jew and Gentile are not found in the original texts of the bible.
