“And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him.”
King James Version (KJV)
8:38 And they both went down - Out of the chariot. It does not follow that he was baptized by immersion. The text neither affirms nor intimates any thing concerning it.
Ac 8:38 They both went down into the water. Abbott states: ``The original undoubtedly implies a going, not to, but into, the water.'' And Ripley says: ``No sufficient reason can be given why the parties went down into the water, but for the sake of the immersion of the new convert.''
