Acts 8:29-32, 34-38

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. Now this was the passage of Scripture which he was reading: “LIKE A SHEEP HE WAS LED TO THE SLAUGHTER; AND AS A LAMB BEFORE ITS SHEARER IS SILENT, SO HE DOES NOT OPEN HIS MOUTH.

The eunuch replied to Philip, “Please tell me, about whom does the prophet say this? About himself or about someone else?” Then Philip spoke and beginning with this Scripture he preached Jesus to him [explaining that He is the promised Messiah and the source of salvation]. As they continued along the road, they came to some water; and the eunuch exclaimed, “Look! Water! What forbids me from being baptized?” [Philip said to him, “If you believe with all your heart, you may.” And he replied, “I do believe that Jesus Christ is the Son of God.”] And he ordered that the chariot be stopped; and both Philip and the eunuch went down into the water, and Philip baptized him.
