Another time he went into the synagogue, and a man with a shriveled hand was there.  Some of them were looking for a reason to accuse Jesus, so they watched him closely to see if he would heal him on the Sabbath. Jesus said to the man with the shriveled hand, “Stand up in front of everyone.” Then Jesus asked them, “Which is lawful on the Sabbath; to do good or to do evil, to save life or to kill?” But they remained silent.

Here is the Sabbath issue again.  Even in the original Law, there was provision for helping your neighbor’s ox out of a ditch if it fell in on a Sabbath.  This is a human being with a need.  Jesus heals the man’s hand.  For this, they go out to plot how to kill Jesus. (vs.6)

Jesus is teaching that love and mercy rise above the following of the letter of the law, especially if following the letter of the law prohibits us from sharing God’s love and mercy with a person in need.
