And he looked around at them with anger, grieved at their hardness of heart, and said to the man, “Stretch out your hand.” He stretched it out, and his hand was restored. The Pharisees went out and immediately held counsel with the Herodians against him, how to destroy him.
ESV Mark 3:5-6
Frustrated by their hearts and attitude, for they prefer to insist to hold on tradition and being legalistic rather than letting someone getting healed. For the Pharisees, it’s better to not do good on Sabbath day rather than doing something good on Sabbath. Jesus then healed the man with the withered hand regardless.
The Pharisees reaction? They quickly departed and held counsel with Herod’s people to eliminate Jesus. Do you notice the irony? The Pharisees forbid Jesus to do good on the Sabbath, but they’re actually doing evil thing on Sabbath day instead by planning how to kill Jesus. Truly what Jesus asked was true “Is it lawful on the Sabbath to do good or to do harm, to save life or to kill?”
