'Water' in the Bible

For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.

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?

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.

And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing.

Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?

Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost.
