Exodus 20:7-11

7 "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.

8 "Remember the Sabbath day, to keep it holy.  9 You shall labor six days, and do all your work,  10 but the seventh day is a Sabbath to Yahweh your God. You shall not do any work in it, you, nor your son, nor your daughter, your man-servant, nor your maid-servant, nor your cattle, nor your stranger who is within your gates;  11 for in six days Yahweh made heaven and earth, the sea, and all that is in them, and rested the seventh day; therefore Yahweh blessed the Sabbath day, and made it holy.
