first mention of the sabbath in the bible
Biblical Sabbath Observation and remembrance of Sabbath is one of the Ten Commandments (the fourth in the original Jewish, the Eastern Orthodox, and most Protestant traditions, the third in Roman Catholic and Lutheran traditions), sometimes referred to individually as the Sabbath Commandment. Most people who observe Biblical Sabbath regard it as having been made for man (Mark. 2:27) at Creation (Ex. 20:8–11), and instituted as a perpetual covenant for the people of Israel (Ex. 31:13-17, Ex. 23:12, Deut. 5:13-14), a rule that also applies to proselytes, and a sign respecting two events: the seventh day, during which God rested after having completed Creation in six days (Gen. 2:2-3, Ex. 20:8-11), and God's deliverance of the Israelites from Egypt (Deut. 5:12-15).
Workweek and weekend The Christian Sabbath was just one day each week, but the preceding day (the Jewish Sabbath) came to be taken as a holiday as well in the twentieth century. This shift has been accompanied by a reduction in the total number of hours worked per week, following changes in employer expectations. The present-day concept of the 'week-end' first arose in the industrial north of Britain in the early part of nineteenth century[1] and was originally a voluntary arrangement between factory owners and workers allowing Saturday afternoon off from 2pm in agreement that staff would be available for work sober and refreshed on Monday morning.[2] The Amalgamated Clothing Workers of America Union was the first to successfully demand a five-day work week in 1929.
