John Gill Commentary Acts 10:18

"and called and asked whether Simon, who was surnamed Peter, were lodging there." — Acts 10:18 (ASV)

And called, and asked
That is, they called to the people of the house, Simon's family; and in a civil and courteous manner asked them,

whether Simon, which was surnamed Peter ;
which they said to distinguish him from Simon the master of the house, and as Cornelius was directed, and they were instructed by him: concerning him they inquired, whether he

were lodged there ;
the Ethiopic version adds, without any foundation for it, "and the place where they called at was Peter's lodging room".
