«The heaven and the earth were finished, and all their array. On the seventh day God finished the work that He had been doing, and He ceased on the seventh day from all the work that He had done. And God blessed the seventh day and declared it holy, because on it God ceased from all the work of creation that He had done.» (Genesis 2, 1-3).
«Remember the sabbath day and keep it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath of the LORD your God: you shall not do any work—you, your son or daughter, your male or female slave, or your cattle, or the stranger who is within your settlements. For in six days the LORD made heaven and earth and sea, and all that is in them, and He rested on the seventh day; therefore, the LORD blessed the sabbath day and hallowed it. » (Exodus 20, 8-11).
