unknown, one Talmudic tradition is that the book is a parable written by Moses

“ There is none like him on earth, an innocent and honest man, who fears God and avoids evil. He still holds on to his innocence, [even though] you incited me to harm him for no reason."
4 And the Accuser answered Yahweh and said: "Skin for skin [7] ! A man would give everything he has for his life.
5 But extend your hand and touch his bones and flesh, and see if he doesn't curse [8] you to your face!"
6 And Yahweh said to the Accuser: "He is in your power [9] ,but watch for his life." ”

“ Chapter 1 1 There was a man in the land of Uz, and his name was Job. This man was innocent and honest and God-fearing and avoided evil.
2 And seven sons were born to him, and three daughters. 3 And his livestock were seven thousand sheep, three thousand camels and five hundred pairs of cattle, and five hundred she-mules. And many laborers, and this man became bigger than all the men of old. [1]
4 And his sons went and made a feast, each man's household his day, and they sent out and called to their three sisters to eat and to drink with them. ”

“ Your sons and daughters are eating and drinking wine in the household of their eldest brother. 19 And here a great wind came from over the savanna, and touched the four corners of the house, and it fell on the boys and they died ”
