"And through the hands of the apostles many signs and wonders were done among the people.
And they were all with one accord in Solomon's Porch.
Yet none of the rest dared join them, but the people esteemed them highly.
And believers were increasingly added to the Lord, multitudes of both men and women, so that they brought the sick out into the streets and laid them on beds and couches, that at least the shadow of Peter passing by might fall on some of them.
Also a multitude gathered from the surrounding cities to Jerusalem, bringing sick people and those who were tormented by unclean spirits, and they were all healed."
Acts 5:12-16
The transfer of healing power, even through the shadow of Peter is similar to the transfer of healing power which came from Jesus through His garment.
They were all healed.
The disciples had the same anointing, power and authority as Jesus did, so they were seeing the same kind of results Jesus did.
