They did not charge our Lord with healing on the sabbath, for He would have replied that if an ox or an ass of theirs had fallen into a pit, would not they have taken it out on the sabbath day: but they addressed the man as he was carrying his bed, as if to say, Even if the healing could not be delayed, why enjoin the work? He shields himself under the authority of his Healer: He that made me whole, the Same said unto me, Take up thy bed, and walk: meaning, Why should not I receive a command, if I received a cure from Him?
