Chapter 26 — Part III: The Decalogue — The Third Commandment
Section 17. Sabbath — We now come to the meaning of the word sabbath. Sabbath is a Hebrew word which signifies cessation. To keep the Sabbath, therefore, means to cease from labor and to rest. In this sense the seventh day was called the Sabbath, because God, having finished the creation of the world, rested on that day from all the work which He had done. Thus it is called by the Lord in Exodus.
