13 “Speak to the Israelites and tell them, ‘Especially, you are to keep my sabbaths,+ for it is a sign between me and you during your generations in order that you may know that I, Jehovah, am sanctifying you.

15 Remember that you became a slave in the land of Egypt and that Jehovah your God brought you out of there with a mighty hand and an outstretched arm.+ That is why Jehovah your God commanded you to observe the Sabbath day.
