Glastonbury is said to be the birthplace of

37:3 Now Israel loved Joseph more than all his children,
because he was the son of his old age: and he made him a coat of many colors.
37:4 And when his brothers saw that their father loved him
more than all his brothers, they hated him, and could not
speak peaceably to him.
37:23 And it came to pass, when Joseph was come to his
brothers, that they stripped Joseph out of his coat, his coat

pit was empty, there was no water in it.
37:25 And they sat down to eat bread: and they lifted up
their eyes and looked, and, behold, a company of
Ishmeelites came from Gilead with their camels bearing
spices and balm and myrrh, going to carry it down to Egypt.
37:26 And Judah said to his brothers, What profit is it if

PLATE 55 of Jerusalem:
"the Eternal Man Walketh among us, calling us his Brothers & his Friends:
Forbidding us that Veil which Satan puts between Eve & Adam
By which the Princes of the Dead enslave their Votaries
Teaching them to form the Serpent of precious stones & gold
To sieze the Sons of Jerusalem & plant them in One Mans Loins
To make One Family of Contraries: that Joseph may be sold
Into Egypt: for Negation; a Veil the Saviour born & dying rends."
