Question

what is mean by "the third possessor ?" What role did Jacob's wise mother play to make him the third possessor?​

Answer 1

She told him to take the dish prepared by her and give it to his father in place of his brother. And because his father was blind he gave him the blessing.

And he became the third possessor

Answer 2

Esau and Jacob were Issac’s sons. Issac wanted to bless his elder son Esau but would do so after he brought him some savoury meant. Jacob’s mother Rebecca overheard this conversation. She wanted to get this blessing for Jacob. She told Jacob to fetch two goats to make a savoury dish. Rebecca then asked Jacob to go to his blind father with the savoury meat. In this way, Jacob, through the crafty assistance of his mother, got the blessing of his father.
