“What does it mean that the Sabbath was made for man and not man for the Sabbath?”
The Sabbath was a weekly day of rest for the people of Israel instituted by God through Moses at Mount Sinai. Keeping it is the fourth of the Ten Commandments. Its basis is the creation week of Genesis 1-2: “For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.”
