You may look it up.
Even the pharisees on the scene were not accusing them of theft , the law would have been for them on that, but even the slightest work on the sabbath was an infraction.
I think the point Jesus made is valid, the law needs int erpretation with sense and good judgement , not niggleing attention to detail. When applied so as to operate against the spirit and intention of the law, the law can be made harmfull to the people.
