'Holy Spirit' in the Bible

The birth of [Jesus] Christ came about thus. His mother Mary was betrothed to Joseph, but before they came together she was discovered to be pregnant by the holy Spirit.

but after he had planned this, there appeared an angel of the Lord to him in a dream saying, "Joseph, son of David, fear not to take Mary your wife home, for what is begotten in her comes from the holy Spirit.

I baptize you with water for repentance, but he who is coming after me is mightier, and I am not fit even to carry his sandals; he will baptize you with the holy Spirit and fire.

Whoever says a word against the Son of man will be forgiven, but whoever speaks against the holy Spirit will never be forgiven, neither in this world nor in the world to come.

go and make disciples of all nations, baptize them in the name of the Father and the Son and the holy Spirit,
