This is a view from the Jewish side. The territory used to be open to the sky, but now it is closed and used as a synagogue. A green door leads to the graves of Yaqoob (peace be upon him) and Lia [Leah], who was one of his wives.
Yaqoob (peace be upon him) is mentioned by name 16 times in the Quran.
Yaqoob (peace be upon him) was the son of Ishaq (peace be upon him) and his wife Rifaqah [Rebekah] and was born in Palestine. He spent his life in the footsteps of his father and grandfather.
Yaqoob (peace be upon him) had four wives and twelve sons, who became the progenitors of the twelve tribes of Israel. Seven of his sons were from his wife Leah, who is buried next to him. The Prophet Yusuf (Peace be upon him) and Benjamin were from Rachel [Rachel].
After Yusuf (peace be upon him) became the keeper of the storehouses in Egypt, Yaqoob (peace be upon him), together with his whole family, went to Egypt at the invitation of his son and settled there. He died at the age of 140 and was returned and buried in Hebron (al-Khalil) according to his will.
When the Prophet Yaqoob (peace be upon him) was on the verge of death, he was called his sons and talked with them. This is mentioned in the following verses of the Qur’an in Sura al-Baqara: “Ibrahim prescribed the same thing to his sons, as well as to Yaqoob (saying):“ Oh my sons! Lo! Allah chose for you the true religion, so do not die, except as people who surrendered (to Him) or you were present when death came to Yaqoob, when he told his sons: What will you worship after me? They said: “We will worship your God, the God of your fathers, Ibrahim, Ismail and Ishaq, the One God, and we have surrendered to Him.” [2: 132, 133]
