And behold, there was a man before him who had dropsy. And Jesus responded to the lawyers and Pharisees, saying, “Is it lawful to heal on the Sabbath, or not?” But they remained silent. Then he took him and healed him and sent him away. And he said to them, “Which of you, having a son or an ox that has fallen into a well on a Sabbath day, will not immediately pull him out?” And they could not reply to these things.
Luke 14:2-5 (ESV)
Jesus obliterates legalism.
