The Book of Jubilees 32:2
And Jacob said: 'Lord, how can I remember all that I have read and seen 'And he said unto him: 'I will bring all things to thy remembrance.' And he went up from him, and he awoke from his sleep, and he remembered everything which he had read and seen, and he wrote down all the words which he had read and seen. And he celebrated there yet another day, and he sacrificed thereon according to all that he sacrificed on the former days, and called its name 'Addition,' for this day was added and the former days he called 'The Feast '. And thus it was manifested that it should be, and it is written on the heavenly tablets: wherefore it was revealed to him that he should celebrate it, and add it to the seven days of the feast. And its name was called 'Addition,' because that it was recorded amongst the days of the feast days, according to the number of the days of the year. And in the night, on the twenty-third of this month, Deborah Rebecca's nurse died, and they buried her beneath the city under the oak of the river, and he called the name of this place, 'The river of Deborah,' and the oak, 'The oak of the mourning of Deborah.' And Rebecca went and returned to her house to his father Isaac, and Jacob sent by her hand rams and sheep and he-goats that she should prepare a meal for his father such as he desired. And he went after his mother till he came to the land of Kabratan, and he dwelt there. And Rachel bare a son in the night, and called his name 'Son of my sorrow '; for she suffered in giving him birth: but his father called his name Benjamin, on the eleventh of the eighth month in the first of the sixth week of this jubilee. And Rachel died there and she was buried in the land of Ephrath, the same is Bethlehem, and Jacob built a pillar on the grave of Rachel, on the road above her grave.
