HOLY GHOST-HOLY SPIRIT

The Holy Ghost was a new type Holy Spirit that would only come after the
cross. After Jesus was glorified (on the cross).

[Jhn 7:39
39 (But this spake he of the Spirit, which they that believe on him should
receive: for the Holy Ghost was not yet [given]; because that Jesus was not yet
glorified.)
[Jhn 14:26
26 But the Comforter, [which is] the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
[Jhn 16:4, 7-14
4 "But these things I have told you, that when the time comes, you may
remember that I told you of them. And these things I did not say to you at the
beginning, because I was with you. ...
7 "Nevertheless I tell you the truth. It is to your advantage that I go away;
for if I do not go away, the Helper will not come to you; but if I depart, I
will send Him to you.
8 "And when He has come, He will convict the world of sin, and of
righteousness, and of judgment:
9 "of sin, because they do not believe in Me;
10 "of righteousness, because I go to My Father and you see Me no more;
11 "of judgment, because the ruler of this world is judged.
12 "I still have many things to say to you, but you cannot bear [them]
now.
13 "However, when He, the Spirit of truth, has come, He will guide you into
all truth; for He will not speak on His own [authority], but whatever He hears
He will speak; and He will tell you things to come.
14 "He will glorify Me, for He will take of what is Mine and declare [it] to
you
