The Double portion has always intrigued me. It’s mentioned in the bible and why would you not want it? It sounds great and isn’t two better than one? The firstborn blessing was given to the first born son in the Old Testament. It originated from the blessings of Abraham being passed onto Isaac, then from Isaac to Jacob. Jacob was not the first born but saw the potential of such a blessing and stole it from Esau. It seems that this double portion blessing was then established in the Tribes of Israel.
