Acts 8:35-38

And Philip opened his mouth, and beginning from this scripture, preached unto him Jesus. And as they went on the way, they came unto a certain water; and the eunuch saith, Behold, here is water; what doth hinder me to be baptized? And he commanded the chariot to stand still: and they both went down into the water, both Philip and the eunuch; and he baptized him.
