Adam Clarke on Acts 9:34

Jesus Christ maketh thee whole - Not Peter, for he had no power but what was given him from above. And, as an instrument, any man could heal with this power as well as Peter; but God chose to put honor upon those primitive preachers of his word, that men might see that they were commissioned from heaven.

Arise, and make thy bed - Give now full proof that Jesus Christ Has made thee whole, by arising, and by making thy bed. He was at home, and therefore was not commanded, as the paralytic person, to take up his bed; but he was ordered to make it - strew it afresh, that all might see that the cure was perfect.
