Luke 17:14

And when he saw them, he said unto them, Go and show yourselves unto the priests. And it came to pass, as they went, they were cleansed.

The marvelous diversity of methods in Jesus' miracles is a mark of their divine originality. Some were healed in one circumstance, some in others; most were healed instantaneously; one or two were healed in stages; some were touched by Jesus, others were not; some were commanded to tell it, others forbidden to tell it; some upon the basis of their own faith, others upon the faith of friends; some were healed in his presence, others in absentia; and, true to such diversity, there is a unique angle here, in that they were commanded to go show themselves to the priests (a necessary requirement of the Law, before they could be pronounced cured and reenter society); and they were healed en route! No forger could have imagined a circumstance like this.
