'Holy Spirit' in the Bible

Now the birth of Jesus Christ was this way (for His mother Mary was betrothed to Joseph) before they came together, she was found to be with child by the Holy Spirit.

And as he thought upon these things, behold, the angel of the Lord appeared to him in a dream, saying, Joseph, son of David, do not fear to take to you Mary as your wife. For that in her is fathered of the Holy Spirit.

I indeed baptize you with water to repentance. But He who comes after me is mightier than I, whose sandals I am not worthy to carry. He shall baptize you with the Holy Spirit and with fire;

Therefore I say to you, All kinds of sin and blasphemy shall be forgiven to men, but the blasphemy against the Holy Spirit shall not be forgiven to men.

And whoever speaks a word against the Son of Man, it shall be forgiven him. But whoever speaks against the Holy Spirit, it shall not be forgiven him, either in this world or in the world to come.

Therefore go and teach all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
