'Advocate' in the Bible

And I will ask the Father, and he will give you another Advocate, in order that he may be with you {forever}--

But the Advocate, the Holy Spirit, whom the Father will send in my name--that one will teach you all [things], and will remind you of everything that I said to you.

"When the Advocate comes, whom I will send to you from the Father--the Spirit of truth, who proceeds from the Father--that one will testify about me.

But I tell you the truth, it is better for you that I go away. For if I do not go away, the Advocate will not come to you; but if I go, I will send him to you.

My little children, I am writing these [things] to you in order that you may not sin. And if anyone sins, we have an advocate with the Father, Jesus Christ the righteous [one],
