Acts 8:36-38 NASB
As they went along the road they came to some water; and the eunuch *said, “Look! Water! What prevents me from being baptized?” [And Philip said, “If you believe with all your heart, you may.” And he answered and said, “I believe that Jesus Christ is the Son of God.”] And he ordered the chariot to stop; and they both went down into the water, Philip as well as the eunuch, and he baptized him.
