Remember the sabbath day, to keep it holy. Six days you shall labor, and do all your work; but the seventh day is a sabbath to the Lord your God; in it you shall not do any work.

The sabbath was made for man, not man for the sabbath; so the Son of Man is lord even of the sabbath.

2168 The third commandment of the Decalogue recalls the holiness of the sabbath: "The seventh day is a sabbath of solemn rest, holy to the LORD."
