The Jews, or more specifically those from the 12 tribes of Israel, are a Semitic *race* (ethnic group) descended from Abraham, Isaac, and Jacob/Israel. Their nation was called Israel because of their ancestor Jacob/Israel. They were all Hebrews descended from Eber. There is no getting around this FACT.
Their religion was that which was under the Old Covenant (the Law of Moses), which included the tabernacle and the temple. Israel was meant to be a theocracy, but because they wanted a human king, they got him (Saul), and subsequently Israel split into the Northern Kingdom (kingdom of Israel) and the Souther Kingdom (the kingdom of Judah). Jesus of Nazareth was the King-Messiah of Israel, a Hebrew of the Hebrews
This simply means that there is only ONE HUMAN RACE, with many ethnic groups called *races* (rightly or wrongly). Which also means that racism is evil, because God views all of humanity as simply two groups -- the saved and the lost. During the Church age, the Jews are not being treated by God as a separate entity, but Anti-Semitism is also evil.
