[26] Now an angel of the Lord said to Philip, “Rise and go toward the south 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:

“Like a sheep he was led to the slaughter
and like a lamb before its shearer is silent,
so he opens not his mouth.
[33] In his humiliation justice was denied him.
Who can describe his generation?
For his life is taken away from the earth.”

[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?” [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.
