Job was a man who lived in the land of Uz he was very wealthy and had a good life but one thing he feared God and turned away from evil.
Satan thinks people only like God because of the blessings he gives them and since job was rich Satan wanted to test him to prove God his reason.
Satan takes jobs property and kids: while the kids were drinking wine at there older brothers house a messenger came telling job the oxen were plowing and the donkeys feeding beside them while Job was talking to the messenger another came and said the fire of God fell from heaven and burned all the sheep and the servants and consumed them.
As Job was trying to talk another messenger came along, the Chaldeans came and raided the camels and struck the servants with the edge of a sword an I have escaped to tell you, then has he tried to talk once more another messenger came and said your kids were at there brothers house a wind came throught the house and killed all of them.
God have gave job diseases, finally job said: "Naked I came from my mothers womb naked I shall return. The lord gave, the lord has taken away; blessed be name of the lord".
Job never gave no sin to god or wrong after all of the events.
The life lesson of jobs story is about that God knows how his life and what will happen and he will reward evil and good, The spiritual lesson he chose faith in the midst of suffering.
Job had seven sons and three daughters and a wife (I am not aware of the names).
