Philip gets into action. The Spirit sends him to the man: Go over and join this chariot.
Chariot (“harma”): two-wheeled travel chariot with driver, or perhaps a war chariot (such as in Revelation 19:9) drawn by one or two horses. This chariot also appears in Acts 8:28–29, Acts 8:31, Acts 8:39. Perhaps there are more chariots and horses, as there are also security guards and personnel travelling with the Ethiopian.
29 And the Spirit said to Philip, “Go over and join this chariot.”
