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).
Lord of the Sabbath Matthew makes two statements regarding Jesus' view of his role: he is Lord [even] of the Sabbath and also he is 'one greater than the Temple'.[8] There are different interpretations of the reference to the Son of man statement in Matthew 12:1-8 that "the Son of man is Lord of the Sabbath". It may mean that Jesus is claiming to be the Lord or that his Apostles are entitled to do as they wish on the Sabbath.[9]
