The verb dierōtaō means to inquire carefully or to find out through questioning — a thorough investigation by asking. In Acts 10:17, it describes the men sent by Cornelius who found Peter's lodging through careful inquiry, fulfilling the divine orchestration of Peter's encounter with the first Gentile household.
The meeting between Peter and Cornelius is one of Acts' most pivotal moments: the official opening of the gospel to the Gentiles. That the messengers found Peter through diligent inquiry (dierōtaō) underscores the human side of divine providence — God works through ordinary means, through asking questions and getting directions. The Spirit's supernatural vision and voice were accompanied by the practical human act of finding the address.
