Chapter for transforming into a snake de Nile

I am a long lived snake,i pass the night and am reborn every day
i am the snale which is in the limits of the earth
i pass the night and am reborn,renewed and rejuvenated every day
i am a crocodile immersed in dread
i am the crocodile who takes by robbery
i am the great and mighty loathsome reptile
who is in the bitter waters
i am the lord of those who bow down in sekhem
