Acts 3:8

Verse 8. And he leaping up. This was a natural expression of joy; and it was a striking fulfillment of the prophecy in Isa 35:6: "Then shall the lame man leap as an hart." The account here given is one that is perfectly natural. The man would be filled with joy, and would express it in this manner. He had been lame from a child; he had never walked; and there was more in the miracle than merely giving strength. The act of walking is one that is acquired by long practice. Children learn slowly. Casper Hauser, lately discovered in one of the cities of Germany, who had been confined in prison from a child, was unable to walk in an easy way when released, but stumbled in a very awkward manner.
