John Chrysostom

"And he took him by the right hand, and lifted him up." Such was also the way of Christ. Often He healed by word, often by an act, often also He stretched forth the hand, where men were somewhat weak in faith, that the cure might not appear to be spontaneous. "And he took him by the right hand, and lifted him up." This act made manifest the Resurrection, for it was an image of the Resurrection.

Homily on Acts 8 ↗

Theophylact of Ohrid

"And he took him by the right hand, and lifted him up." This manner of healing pointed to the resurrection, since it was a figure of the resurrection.

Commentary on Acts ↗

Oecumenius

Which Christ often, when healing those who are in a more imperfect state, did not only heal by word but also by touch, this now Peter likewise does. But also through "he raised him," the mystery of the resurrection is demonstrated, and so that what happened should not seem to be from coincidence or winging it. He therefore rose, either because some doubted what had happened, and, testing, made the foundation firmer and more secure, or because he did not yet know how to walk. [CHRYSOSTOM]

Commentary on Acts ↗

Bede

And immediately his feet and ankle bones were strengthened. The term 'bases' is Greek in origin, and it is placed thus in Greek, which in Latin means 'supports': by which term it indicates that his steps were strengthened, just as some have also translated it into Latin. But it must be known that steps are properly called διαβήματα or πορίαι among the Greeks.
