Acts 8:36-39

And while they were going along the way, they arrived at a certain water source. And the eunuch said: "There is water. What would prevent me from being baptized?" Then Philip said, "If you believe from your whole heart, it is permitted." And he responded by saying, "I believe the Son of God to be Jesus the Christ." And he ordered the chariot to stand still. And both Philip and the eunuch descended into the water. And he baptized him. And when they had ascended from the water, the Spirit of the Lord took Philip away, and the eunuch did not see him anymore. Then he went on his way, rejoicing.
