'Water' in the Bible

For John indeed baptised with water, but ye shall be baptised with the Holy Spirit after now not many days.

And as they went along the way, they came upon a certain water, and the eunuch says, Behold water; what hinders my being baptised?

And he commanded the chariot to stop. And they went down both to the water, both Philip and the eunuch, and he baptised him.

But when they came up out of the water the Spirit of the Lord caught away Philip, and the eunuch saw him no longer, for he went on his way rejoicing.

Can any one forbid water that these should not be baptised, who have received the Holy Spirit as we also did?

And I remembered the word of the Lord, how he said, John baptised with water, but ye shall be baptised with the Holy Spirit.
