Matthew 12:10
And a man was there with a withered hand. And they asked him: is it lawful to heal on the Sabbath? — so that they might accuse him. The withered hand is presented as a test case rather than a healing request — the Pharisees ask whether healing on the Sabbath is lawful, not because they want the man healed, but to find a charge against Jesus. The man with the withered hand is instrumentalized by the Pharisees as a legal trap. Jesus' response will address both the legal question and the man's condition.
