'Concerning' in the Bible

So a dispute occurred on the part of John's disciples with a Jew concerning purification.

And there was a lot of grumbling concerning him among the crowds; some were saying, "He is a good [man]," but others were saying, "No, but he deceives the crowd."

Now he said this concerning the Spirit, whom those who believed in him were about to receive. For the Spirit was not yet [given], because Jesus had not yet been glorified.)

So the Pharisees said to him, "You testify concerning yourself! Your testimony is not true."

Jesus answered and said to them, "Even if I testify concerning myself, my testimony is true, because I know where I have come from and where I am going. But you do not know where I have come from or where I am going.

I am the one who testifies concerning myself, and the Father who sent me testifies concerning me."

I have many [things] to say and to judge concerning you, but the one who sent me is true, and [the things] which I heard from him, these [things] I say to the world."

Who among you convicts me concerning sin? If I am telling the truth, {why} do you not believe me?

So the Jews did not believe concerning him that he had been blind and received sight, until they summoned the parents of the one who received sight.

The Jews answered him, "We are not going to stone you concerning a good deed, but concerning blasphemy, and because you, [although you] are a man, make yourself [to be] God!"

So many of the Jews came to Martha and Mary in order to console them concerning their brother.)

And [when he] comes, he will convict the world concerning sin and concerning righteousness and concerning judgment:

concerning sin, because they do not believe in me,

and concerning righteousness, because I am going away to the Father and you will see me no more,

and concerning judgment, because the ruler of this world has been condemned.
