Albert Barnes Commentary Acts 11:14

"who shall speak unto thee words, whereby thou shalt be saved, thou and all thy house." — Acts 11:14 (ASV)

And all your house. Your family. This is a circumstance which is omitted in the account in Acts 10. It is said, however, in Acts 10:2, that Cornelius feared God with all his house. And it is evident from Acts 10:48 that the family also received the ordinance of baptism and was received into the church.
