The sabbath was first described in the biblical account of the seventh day of creation. Observation and remembrance of the sabbath is one of the Ten Commandments (the fourth in the Eastern Orthodox and most Protestant traditions, the third in Roman Catholic and Lutheran traditions). Most people who observe first-day or seventh-day sabbath regard it as having been instituted as a perpetual covenant: "Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant." (Exodus 31:13-17) (see also Exodus 23:12, Deuteronomy 5:13-14)) This rule also applies to strangers within their gates, a sign in respect for the day during which God rested after having completed creation in six days (Genesis 2:2-3, Exodus 20:8-11).
