The Greek Araps (Ἄραψ) means 'Arab' or 'Arabian' — a person from the region of Arabia. It appears in Acts 2:11 among the list of nations present at Pentecost who heard the disciples speaking in their own languages. The inclusion of Arabs in the Pentecost list is significant for the universal scope of the Spirit's outpouring.
The list of nations at Pentecost in Acts 2 is a deliberate reversal of Babel. At Babel, one language was fractured into many as judgment; at Pentecost, many languages are unified in worship as redemption. Arabs are explicitly included — heirs of Ishmael, long-standing neighbors and sometimes rivals of Israel — now hearing 'the wonders of God' in their own tongue. The Spirit makes no ethnic exceptions. The gospel at Pentecost begins with a catholic (universal) sweep: Parthians, Medes, Elamites, Egyptians, Libyans, Romans, Cretans, and Arabs — all receive the first announcement of God's new-creation work in Christ. The Spirit is not the property of one nation but the gift to all flesh (Acts 2:17).
