'Holy Spirit' in the Bible

I have baptized you in water, but he shall baptize you in the Holy Spirit."

but he who blasphemes against the Holy Spirit is never forgiven. Nay, he is in the grasp of an eternal sin."

David himself said in the Holy Spirit, "The Lord said to my Lord, 'Sit at my right hand until I make thy foes the footstool of thy feet.'

When, however, they are leading you all to trial, do not worry beforehand about what you are to say, but whatever is given you in that hour, that say, for it is not you who speak, but the Holy Spirit.
