En ce temps-là, Ezéchias fut atteint d’une maladie mortelle. Le prophète Isaïe, fils d’Amoç, lui rendit visite et lui dit: "Ainsi parle l’Éternel: Donne tes ordres à ta maison, car tu vas mourir; tu ne te rétabliras pas."

The meaning of our opening aggadah is as follows. If you refrain from contact with your wife during the seven days of the menstrual cycle, tum-ah, you will merit the blessing of the eighth day, i.e. circumcision, which symbolises ascendancy over the spirit of impurity, attainment of purity. Since "seven days" represent the "creation cycle," the number seven always reminds man both of his duties and of his limitations on this planet.
