One of the key lessons from the blessings of the 12 founders of the tribes of Israel in Torah reading ויחי Vayechi (“he lived,” Gen. 47:28–50:26) is that ancestry doesn’t mean much if each generation doesn’t carry on the legacy handed down. We can learn from these blessings and from the final messages of King David for Solomon (1Kings 2:1–12) and of Messiah Yeshua (Christ Jesus) for the Twelve (John 13–17) what Heaven wants us to pass on to our children and to the world.
We all have to choose spiritually and physically (belief in action) to follow what is right to receive the blessings that God has for us to further the Kingdom of Heaven on Earth.
