“The blessing of all people
Came to rest
On the head of Jacob.
The covenant
Came to rest
On the head of Jacob.
The Most High acknowledged him
With his blessings.
He gave him his inheritance.
He divided his portions.
He distributed them
Among the twelve tribes.”
The stories about Isaac and Jacob can be found in Genesis, chapters 25-36. Thus the blessings and covenant of Abraham and Isaac came to Jacob, the son of Isaac. The Most High God acknowledged and blessed Jacob as he received his inheritance that was divided among the 12 tribes. Sirach has no indication about his 12 sons and their activities.
