In Judaism, the number 8 is indicative of the supernatural because 8 is the next integer larger than 7, the Sabbath, or the day G-d completed the Creation. In those seven days G-d created the heavens, earth, land, water, sun, moon, stars, flora, reptiles, sea life, amphibians (not explicitly mentioned), freaks of nature like the duck-billed platypus, birds, and mammals, culminating with Woman. Beyond the seven days of the Natural lies the Supernatural.

In gematriah, or Hebrew numerology, eight represents the letter chet, the eigth letter of the Hebrew alphabet. Chet is pronounced with a guttural tone on the 'ch', a property not found in the English language.
