Was Noah Jewish? If not, when did God start the Jewish nation?
Noah was not Jewish. If he was, we would all be Jews since the flood destroyed everyone expect for Noah and his family (Genesis 5:29-9:1). In Genesis 9:1-7, we find that God tells Noah to populate the earth.
The Jewish race started with Jacob (Gen. 32:28). Even though circumcision started with Abraham, one of the key signs of a Jew, Abraham was not the direct father of the Jews. Abraham was the father of both the Jews and the Arabs since his sons were Isaac and Ishmael (1 Chron. 1:28). The Jews are descendants of Isaac and the Arabs are descendants of Ishmael. Therefore, it is not surprising that the Jews in Jesus’ day considered Abraham to be their father. Listen to a conversation between some Jews and Jesus.
They answered and said to Him, “Abraham is our father.” Jesus said to them, “If you are Abraham’s children, do the deeds of Abraham. (NASB) John 8:39
The name “Israel” comes from Jacob (Isaiah 48:1) who was the son of Isaac and the grandson of Abraham (Genesis 50:24). Jacob had twelve sons who had many descendants. The descendants are called the twelve tribes of Israel: Reuben, Simeon, Levi, Judah, Issachar, Zebulun, Dan, Joseph, Benjamin, Naphtali, Gad, and Asher. (1 Chronicles 2:1-2). These twelve tribes settled in the promised land of Palestine. Later they formed two kingdoms called the Kingdom of Judah and the Kingdom of Israel. The word Jew comes from the Kingdom of Judah.
