Genesis 2:2-4 NRSV
2:2 And on the seventh day God finished the work that he had done, and he rested on the seventh day from all the work that he had done. 3 So God blessed the seventh day and hallowed it, because on it God rested from all the work that he had done in creation.
4a These are the generations of the heavens and the earth when they were created.
Deuteronomy 5:12-15 NRSV
5:12 Observe the sabbath day and keep it holy, as the LORD your God commanded you. 13 Six days you shall labor and do all your work. 14 But the seventh day is a sabbath to the LORD your God; you shall not do any work--you, or your son or your daughter, or your male or female slave, or your ox or your donkey, or any of your livestock, or the resident alien in your towns, so that your male and female slave may rest as well as you. 15 Remember that you were a slave in the land of Egypt, and the LORD your God brought you out from there with a mighty hand and an outstretched arm; therefore the LORD your God commanded you to keep the sabbath day.
Leviticus 25:1-4 NRSV
25:1 The LORD spoke to Moses on Mount Sinai, saying: 2 Speak to the people of Israel and say to them: When you enter the land that I am giving you, the land shall observe a Sabbath for the LORD. 3 Six years you shall sow your field, and six years you shall prune your vineyard, and gather in their yield; 4 but in the seventh year there shall be a Sabbath of complete rest for the land, a Sabbath for the LORD: you shall not sow your field or prune your vineyard.
