'Holy Spirit' in the Bible

I baptized you with water, but he will baptize you with the Holy Spirit."

But whoever blasphemes against the Holy Spirit does not have forgiveness {forever}, but is guilty of [an] eternal sin"--

David himself said by the Holy Spirit, 'The Lord said to my Lord, "Sit at my right hand, until I put your enemies under your feet." '

And when they arrest you [and] hand you over, do not be anxious beforehand what you should say, but whatever is given to you at that hour, say this. For you are not the ones who are speaking, but the Holy Spirit.
