'Concerning' in the Bible

That which was from the beginning, that which we have heard, that which we have seen with our eyes, that which we beheld, and our hands handled, concerning the Word of life

These things have I written unto you concerning them that would lead you astray.

And as for you, the anointing which ye received of him abideth in you, and ye need not that any one teach you; but as his anointing teacheth you; concerning all things, and is true, and is no lie, and even as it taught you, ye abide in him.

If we receive the witness of men, the witness of God is greater: for the witness of God is this, that he hath borne witness concerning his Son.

He that believeth on the Son of God hath the witness in him: he that believeth not God hath made him a liar; because he hath not believed in the witness that God hath borne concerning his Son.

If any man see his brother sinning a sin not unto death, he shall ask, and God will give him life for them that sin not unto death. There is a sin unto death: not concerning this do I say that he should make request.
