10 but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates.11 For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.
Genesis 2
2 And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done.3 So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation.
