'Sabbath day' in the Bible

Then the Warden of the Synagogue, indignant that Jesus had cured her on a Sabbath, said to the crowd, "There are six days in the week on which people ought to work. On those days therefore come and get yourselves cured, and not on the Sabbath day."

And this woman, daughter of Abraham as she is, whom Satan had bound for no less than eighteen years, was she not to be loosed from this chain because it is the Sabbath day?"

Then He turned to them and said, "Which of you shall have a child or an ox fall into a well on the Sabbath day, and will not immediately lift him out?"
