'Sabbath day' in the Bible

He came to Nazareth, where He had been brought up. As usual, He entered the synagogue on the Sabbath day and stood up to read.

But the leader of the synagogue, indignant because Jesus had healed on the Sabbath, responded by telling the crowd, “There are six days when work should be done; therefore come on those days and be healed and not on the Sabbath day.”

Satan has bound this woman, a daughter of Abraham, for 18 years—shouldn’t she be untied from this bondage on the Sabbath day?”

And to them, He said, “Which of you whose son or ox falls into a well, will not immediately pull him out on the Sabbath day?”
