Genesis 2:1-3 (New Revised Standard Version)
Thus the heavens and the earth were finished, and all their multitude. 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. So God blessed the seventh day and hallowed it, because on it God rested from all the work that he had done in creation.
Luke 14:1-6 (New Revised Standard Version)
On one occasion when Jesus was going to the house of a leader of the Pharisees to eat a meal on the sabbath, they were watching him closely. Just then, in front of him, there was a man who had dropsy. And Jesus asked the lawyers and Pharisees, "Is it lawful to cure people on the sabbath, or not?" But they were silent. So Jesus took him and healed him, and sent him away. Then he said to them, "If one of you has a child or an ox that has fallen into a well, will you not immediately pull it out on a sabbath day?" And they could not reply to this.
