acts 8:36 And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized? - Free Bible Online

      36. See, here is water--more simply, "Behold water!" as if already his mind filled with light and his soul set free, he was eagerly looking out for the first water in which he might seal his reception of the truth and be enrolled among the visible disciples of the Lord Jesus.
      what doth hinder me to be baptized?--Philip had probably told him that this was the ordained sign and seal of discipleship, but the eunuch's question was likely the first proposal of its application in this case. (Ac 8:37 is wanting in the principal manuscripts and most venerable versions of the New Testament. It seems to have been added from the formularies for baptism which came into current use).
