Mark 3
Healing on the Sabbath
He entered again into the synagogue, and there was a man there whose hand was withered. They watched him, whether he would heal him on the Sabbath day, that they might accuse him. He said to the man whose hand was withered, “Stand up.” He said to them, “Is it lawful on the Sabbath day to do good or to do harm? To save a life or to kill?” But they were silent. When he had looked around at them with anger, being grieved at the hardening of their hearts, he said to the man, “Stretch out your hand.” He stretched it out, and his hand was restored as healthy as the other. The Pharisees went out, and immediately conspired with the Herodians against him, how they might destroy him.
In a synagogue on the Sabbath, opponents watch to see whether Jesus will heal a man with a withered hand. Jesus asks whether it is lawful on the Sabbath to do good or harm, to save life or kill; when they stay silent, he heals the man. The Pharisees go out and begin plotting with the Herodians to destroy him.
What does this mean?
A 'withered' hand is shrunken or paralysed. The Herodians were supporters of Herod Antipas and his family; their alliance with the Pharisees, groups that often had little in common, shows how widely opposition was gathering.
Historical context
Jewish teachers agreed that saving a life overrode the Sabbath, but debated what else did. A withered hand was not an emergency, so healing it could wait a day; Jesus' question shifts the issue from what is permitted to what is good.
Why does it matter?
This ends the series of conflicts that began in 2:1, and the plot already points toward Jesus' death. Mark often notes Jesus' emotions: here he looks round 'with anger', grieved at their 'hardness of heart' — a phrase Mark later applies even to the disciples (6:52; 8:17).
