'Holy Spirit' in the Bible

I immersed you in water; but He will immerse you in the Holy Spirit."

but whosoever blasphemes against the Holy Spirit has no forgiveness forever, but is guilty of an eternal sin;

David himself said in the Holy Spirit, 'The Lord said to my Lord, Sit on My right hand, until I put Thy enemies underneath Thy feet.'

And, when they lead you away, delivering you up, be not anxious beforehand what ye shall speak; but whatsoever is given you in that hour, this speak: for it is not ye that speak, but the Holy Spirit.
