Seven

“Through them are said to have formed seven planets, seven days of the week, and seven orifices of the eyes, ears, nostrils, and mouth.

“Seven double letters: Beyt Gimel Dalet Kaf Pey Resh and Tav are the foundation.

He engraved them, He hewed them out, He combined them, He weighed them at opposites, and He formed through them: seven stars in the universe, seven days in the year, seven gates in the body of male and female….and through which He engraved seven universes, seven heavens, seven earths, seven seas, seven rivers, seven Sabbatical years, seven Jubilees, and the Holy Temple.

Therefore He cherished the seventh ones under all the heavens.”
