'Counselor' in the Bible

I will pray to the Father, and he will give you another Counselor, that he may be with you forever, --

But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and will remind you of all that I said to you.

"When the Counselor has come, whom I will send to you from the Father, the Spirit of truth, who proceeds from the Father, he will testify about me.

Nevertheless I tell you the truth: It is to your advantage that I go away, for if I don't go away, the Counselor won't come to you. But if I go, I will send him to you.

"For who has known the mind of the Lord? Or who has been his counselor?"

My little children, I write these things to you so that you may not sin. If anyone sins, we have a Counselor with the Father, Jesus Christ, the righteous.
