The passage describes Philip encountering an Ethiopian eunuch who was reading from the book of Isaiah in his chariot. Philip asks the eunuch if he understands what he is reading, and the eunuch invites Philip to explain it to him. Philip tells him the passage is about Jesus. They come to some water and the eunuch asks to be baptized, so Philip baptizes him. When they emerge from the water, Philip is suddenly taken away by the Spirit, and the eunuch continues on his way rejoicing in his new faith.
