'Water' in the Bible

I indeed have baptised you with water, but he shall baptise you with the Holy Spirit.

And straightway going up from the water, he saw the heavens parting asunder, and the Spirit, as a dove, descending upon him.

For whosoever shall give you a cup of water to drink in my name, because ye are Christ's, verily I say unto you, he shall in no wise lose his reward.

And he sends two of his disciples, and says to them, Go into the city, and a man shall meet you carrying a pitcher of water; follow him.
