Matthew 12:10

‘And behold, a man having a withered hand. And they asked him, saying, “Is it lawful to heal on the sabbath day?” so that they might accuse him.'

As usual Matthew sticks to the bare facts. There was a man with a withered hand there and they challenged Him as to whether it was lawful to heal on the Sabbath day. Note their assumption that He could do it, which underlines their hypocrisy. They knew what He could do and they still opposed Him. They were even more unforgivable than the towns (Matthew 11:20) for they had had the opportunity to think deeply about it. And here their sole aim was to accuse Him. He might have wriggled rather unsatisfactorily out of the previous challenge, but this time if He healed they had got Him. The interpreters of the Law were quite clear on the fact that it was not right to heal on the Sabbath except when life was in danger, and then only to the minimum amount required to preserve life.
