Note 1 at Ac 10:9: The journey from Caesarea to Joppa was about thirty-five miles, more than one day's travel. Cornelius' servants evidently left the next day and arrived at Simon's house around noon two days after Cornelius had seen the angel. When Peter left with the messengers, they departed on the third day after the vision and arrived at Cornelius' house about 3:00 p.m. on the fourth day (Ac 10:30).

Note 2 at Ac 10:9: It was customary for houses of this day to have flat roofs with outside stairways, and people would often use that space to relax or pray.
