John Gill Commentary Acts 14:10

"said with a loud voice, Stand upright on thy feet. And he leaped up and walked." — Acts 14:10 (ASV)

Said with a loud voice
Not only that the man, but that all might hear and attend to the miracle about to be wrought:

stand upright on your feet ;
in five of Beza's manuscripts, and in other copies, and in the Complutensian edition, and in the Syriac version, this clause is introduced with these words, "I say unto thee, in the name of the Lord Jesus Christ"; which is much such a form that Peter used, (Acts 3:6) whereby the virtue of the miracle is ascribed to Christ, and not assumed by the apostle:

and he leaped and walked ;
he sprung up directly from his seat, and leaped about for joy, and walked as well as any other man could.
