Acts 8:26-40 (ESV)

²⁶ Now an angel of the Lord said to Philip, “Rise and go toward the south^[a] to the road that goes down from Jerusalem to Gaza.” This is a desert place. ²⁷ And he rose and went. And there was an Ethiopian, a eunuch, a court official of Candace, queen of the Ethiopians, who was in charge of all her treasure. He had come to Jerusalem to worship ²⁸ and was returning, seated in his chariot, and he was reading the prophet Isaiah. ²⁹ And the Spirit said to Philip, “Go over and join this chariot.” ³⁰ So Philip ran to him and heard him reading Isaiah the prophet and asked, “Do you understand what you are reading?” ³¹ And he said, “How can I, unless someone guides me?” And he invited Philip to come up and sit with him.³² Now the passage of the Scripture that he was reading was this:

³⁴ And the eunuch said to Philip, “About whom, I ask you, does the prophet say this, about himself or about someone else?” ³⁵ Then Philip opened his mouth, and beginning with this Scripture he told him the good news about Jesus. ³⁶ And as they were going along the road they came to some water, and the eunuch said, “See, here is water! What prevents me from being baptized?”^{[b] 38} And he commanded the chariot to stop, and they both went down into the water, Philip and the eunuch, and he baptized him. ³⁹ And when they came up out of the water, the Spirit of the Lord carried Philip away, and the eunuch saw him no more, and went on his way rejoicing. ⁴⁰ But Philip found himself at Azotus, and as he passed through he preached the gospel to all the towns until he came to Caesarea.
