Name of the Holy spirit

Whoever believes in God must know God's name.

What did Jesus teach about God's name?

Matthew 28/18-20 Then Jesus came to them and said,"All authority in heaven and on earth has been given tp me. Therefore go and make disciples of all nations, baptizing them in the name of Father and of Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age"

Jesus said these words, foreseeing the things in the last days when the gospel would be preached to all nations.
In whose name did Jesus tell us to baptize people?

Baptize in the name of the Father and of the Son and of the Holy Spirit.

These words of Jesus show His will to use the three names of the Father and the Son and the Holy Spirit for the salvation of mankind until the end of the age.
Father's name is Jehovah. Son's Name is Jesus. Then, What is the name of Holy Spirit?
Father's name, Jehovah and Son's Name,Jesus are different. Likewise the name of the Holy Spirit is different from the name of the Father or the name of the Son.
In fact Jesus showed the Apostle John a vision, where He said He would have a new name ; not the name of the Father or the name of the Son.

Revelation 3/12 "Him who overcomes I will make a pillar in the temple of my God. Never again will he leave it. I will write on him the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on him my new name."

My 'new' name couldn't be Jesus and Jehovah.

Then whose name is the new name among the names of the Father, the Son, and the Holy Spirit? Holy Spirit's Name.

Jesus clearly testified that the time would come when He would have a new name_ the name of the Holy Spirit.
There is another prophecy about Jesus'new name in Revelation 2.

Revelation 2/17 He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes I will give some of the hidden manna. I will also give him a white on it, known only to him who receives it.

A white stone with a new name written on it is given to those who overcome- God's people who will be saved.

What or who does a "stone" here refer to?

1 Peter 2/4-8
As you come to him [Jesus], the living Stone-rejected by men but chosen by God and precious to him ..... For in Scripture it says: "See, I lay a stone in Zion, a chosen and precious corner stone, and the one who trusts in him will never be put to shame."
now to you who believe, this stone is precious. But to those who do not believe, " The stone the builders rejected has become the capstone," and, "A stone that causes men to stumble and rock that makes them fall." They stumble because they disobey the message - which is also what they were destined for.

Stone= Representing Jesus who came in the flesh. So the new name written on a write stone is Jesus' new name.

Revelation 2/17, too, shows that God's people will receive Jesus' new name, not the name of the Father or the name of the Son.
Therefore, we must believe that there is the name of the Holy Spirit- Jesus' new name, just as Jesus taught us.
And we must also know what Jesus' new name is.

Through the Bible, you can learn more about Jesus' new name - the name of the Holy Spirit.
