Jub-Charles

For this reason it is ordained for the children of Israel that they should afflict themselves on the tenth of the seventh month -on the day that the news which made him weep for Joseph came to Jacob his father- that they should make atonement for themselves thereon with a young goat on the tenth of the seventh month, once a year, for their sins; for they had grieved the affection of their father regarding Joseph his son.
