origin
Yue Se was sold to Egypt at the age of Jacob 108.
Yue Se became prime minister at the age of 30. When Yue Se was 39, Jacob entered Egypt. Jacob was 130 years old at that time. 130-39=9 1 year.
Jacob was born in Yue Se at the age of 9 1.
Jacob lived with his uncle Laban for 20 years. Benjamin was not born when he left. Yue Se was 6 years old, 6+9 1-20=77 years old.
May God grant you wisdom. Amen!
