In the modern world you choose who you want to be. It is not that people in scripture had no choice of their station in life, but that those things handed down from generation to generation would be past through certain tribes. Jacob is ts speaking the blessings to his children. His description prophetic in nature but also a sign task of each child that would be a country of its own in Israel, the promise land. The keeper of tradition of the family was important. It was the role of each son and tribe to pass down not only heritage but the history. Judah would be of the ruling tribe. Kings of Israel would come from the tribe of Israel until Israel was divided. With the intermixing of tribes the history during the division of Israel might still be true, it hard to say, but we know Joseph the husband of Mary was of the tribe of David the tribe of Judah. Yet Joseph was not the biological father of Jesus. Joseph bloodline did not flow through his veins. Point being despite the bloodline of Christ, Joseph would of taught Jesus those things of His tribe. Jesus would be King someday in the land of Israel but not during his original stay in human form. When Christ returns He will be King.

Ties to history, ties to the keeper of the law as well as the priest was found in the ancestry of Jesus. The importance ot the Gentiles would not beyond the prophetic knowledge of it, but to the Jew it would be important evidence that Jesus was the Messiah. This evidence dating after the flood and only grandson of Abraham, more then two thousand years from the birth of Christ. Yet this history would remain because of each tribe and history. The importance is the prophetic nature of God speaking directly through the ancients to the time of Christ. It also evidence of the building stone of faith.

Dear Heavenly Father thank you for prophecy dating over two thousand years. Dating a time period that demonstrates your blessings of heritage to each generation. In Jesus precious name, Amen.
