'Sabbath day' in the Bible

But the leader of the synagogue, in his vexation because Jesus had cured her on the Sabbath, spoke out and said to the crowd, "There are six days on which it is right to work. Come on them and be cured, but not on the Sabbath day."

And did not this woman, who is a descendant of Abraham, whom Satan has kept bound for eighteen years, have to be released from those bonds on the Sabbath day?"
