Deuteronomy 5:13

You shall not take the name of Yahweh your God in vain: for Yahweh will not hold him guiltless who takes his name in vain.

Observe the Sabbath day, to keep it holy, as Yahweh your God commanded you.

but the seventh day is a Sabbath to Yahweh your God, in which you shall not do any work, you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your ox, nor your donkey, nor any of your livestock, nor your stranger who is within your gates; that your male servant and your female servant may rest as well as you.

You shall remember that you were a servant in the land of Egypt, and Yahweh your God brought you out of there by a mighty hand and by an outstretched arm: therefore Yahweh your God commanded you to keep the Sabbath day.
