88:1.6

Certain days of the week were fetishes. For ages Friday has been regarded as an unlucky day and the number thirteen as an evil numeral. The lucky numbers three and seven came from later revelations; four was the lucky number of primitive man and was derived from the early recognition of the four points of the compass. It was held unlucky to count cattle or other possessions; the ancients always opposed the taking of a census, “numbering the people.”
