'Holy Spirit' in the Bible

I indeed immersed you in water, but he will immerse you in Holy Spirit.

But whoever may blaspheme against the Holy Spirit has no forgiveness, into the age, but is deserving of eternal damnation,

For David himself said by Holy Spirit, The Lord says to my Lord, Sit thou at my right hand until I may place thine enemies a footstool of thy feet.

But when they lead you, delivering you up, be not anxious before what ye might speak, nor meditate. But whatever may be given you in that hour, speak ye this, for ye are not who speak, but the Holy Spirit.
