From meta (implying change of place) and pempō (to send). To send for someone, to summon. Used frequently in Acts for official summons — especially in the narrative of Cornelius sending for Peter.
This seemingly ordinary word carries extraordinary theological significance in Acts 10. Cornelius, a Roman centurion, was told by an angel to send for Simon Peter (Acts 10:5). This summons led to the first Gentile Pentecost — the moment when the gospel officially crossed ethnic boundaries. God used a simple act of sending a message to change the course of salvation history.
