No, actually Jesus promoted the lost sheep of the House of Israel. The House of Israel is the ten northern tribes scattered throughout all the nations.
Jesus said “I came only for the LOST SHEEP OF THE HOUSE OF ISRAEL.” not to be confused with the Jews of the House of Judah. Jews only come from the tribe of Judah. The House of Israel is a whole different nation and peoples from the Jews.
Abraham wasn’t a Jew, Isaac wasn’t a Jew, Jacob wasn’t a Jew, Moses wasn’t a Jew. Oh Yeah Jesus was a Jew.
According to what Luke tells us Christ came from the king line, Judah, and the priest line, Levi. Fulfilling that still yet future King of Kings and Lord of Lords. Moses was from the tribe of Levi.
It is a fallacy to teach that the Bible never uses “Israel” to discuss the the combined twelve tribes.
Technically, while the term "Jew" is a contraction of "Judah", it would represent those of the House of Judah entirely, not only the Tribe of Judah. The House of Judah would be those not taken by the Assyrians- Namely Judah, Benjamin, and Levi. The other 10 tribes make up the House of Israel.
