Exodus 20:8-11

8Remember the Sabbath day, to keep it holy:

9You are to labor six days and do all your work,

10but the seventh day is a Sabbath to the Lord your God. You must not do any work — you, your son or daughter, your male or female servant, your livestock, or the resident alien who is within your city gates.

11For the Lord made the heavens and the earth, the sea, and everything in them in six days; then he rested on the seventh day. Therefore the Lord blessed the Sabbath day and declared it holy.
