Acts 8:26-31

But 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). So 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, and he was returning, and sitting in his chariot he was reading [the scroll of] the prophet Isaiah. Then the [Holy] Spirit said to Philip, “Go up and join this chariot.” Philip ran up and heard the man reading the prophet Isaiah, and asked, “Do you understand what you are reading?” And he said, “Well, how could I [understand] unless someone guides me [correctly]?” And he invited Philip to come up and sit with him.
