Again he entered the synagogue, and a man was there with a withered hand. And they watched Jesus, to see whether he would heal him on the Sabbath, so that they might accuse him. And he said to the man with the withered hand, “Come here.” And he said to them, “Is it lawful on the Sabbath to do good or to do harm, to save life or to kill?” But they were silent.
Mark 3: 1-4 ESV
The Pharisees seem to be big fan of Jesus :p
They keep following Jesus everywhere and observing what Jesus do very very closely. Unfortunately they’re doing that too find mistakes in what Jesus do so that they can accuse Jesus. And this time they’re trying to find whether Jesus will heal the man with the withered hand or not. For the pharisees, healing is doing work, and doing work on Sabbath day is unlawful for them. However not to heal someone just because it’s Sabbath day, is an act of legalism, which means following the law or tradition just because it’s the law, and can you still call that doing good? That’s why Jesus asked them whether it’s better to do good or to do harm on Sabbath day? To save life or to kill on Sabbath day?
The Pharisees were silent.
