Acts 8:25-31

25So, when Peter and John had given their testimony and preached the word of the Lord, they started back to Jerusalem, preaching the good news [about salvation] in many Samaritan villages [along the way].

26But an angel of the Lord said to Philip, “Get up and go south to the road that runs from Jerusalem down to Gaza.” (This is a desert road).

27So he got up and went; and there was an Ethiopian eunuch [a man of great authority], a court official of Candace, queen of the Ethiopians, who was in charge of all her treasure. He had come to Jerusalem to worship,

28and he was returning, and sitting in his chariot he was reading [the scroll of] the prophet Isaiah.

29Then the [Holy] Spirit said to Philip, “Go up and join this chariot.”

30Philip ran up and heard the man reading the prophet Isaiah, and asked, “Do you understand what you are reading?”

31And he said, “Well, how could I [understand] unless someone guides me [correctly]?” And he invited Philip to come up and sit with him.
