Acts 8:36-38

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.
