Acts 5:15

Insomuch that they even carried out the sick into the streets, and laid them on beds and couches, that, as Peter came by, at the least his shadow might overshadow some of them.

The sacred author does not tell us that any of the people upon whom Peter's shadow fell were healed; and from this it would appear that the purpose of including this is to emphasize the overwhelming popularity that attached to the Twelve. Adam Clarke took the view that:

I cannot see all the miraculous influence here that others profess to see ... It does not appear that the persons who thus thought and acted were converts already made to the faith of Christ; nor does it appear that any person was healed in this way.[26]

Likewise, Lange refused the premise that people were healed by Peter's shadow, saying:

Luke testified, particularly at the close of Acts 5:16, that Peter performed many miracles of healing, but he does not describe the mode ... It is, however, also possible that in some instances, sick persons, whose faith had prepared them to receive the gift of health, were restored without their actually having been touched by Peter.[27]
