The Seven Day Week in the Hebrew Bible

There is no good evidence tracing the seven day week back to ancient egyptian or mesopotamian practices. But we do see jewish sources making specific reference to things occurring on certain days of the week, specifically on the sabbath day. In jewish literature from around the second century b c e,. may have been related to the revival and promotion of the observance of the sabbathon. And this was surely also shared and promoted by other judean groups at the time.
