'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 did behold, and our hands did handle, concerning the Word of the Life --

These things I did write to you concerning those leading you astray;

and you, the anointing that ye did receive from him, in you it doth remain, and ye have no need that any one may teach you, but as the same anointing doth teach you concerning all, and is true, and is not a lie, and even as was taught you, ye shall remain in him.

If the testimony of men we receive, the testimony of God is greater, because this is the testimony of God that He hath testified concerning His Son.

He who is believing in the Son of God, hath the testimony in himself; he who is not believing God, a liar hath made Him, because he hath not believed in the testimony that God hath testified concerning His Son;

If any one may see his brother sinning a sin not unto death, he shall ask, and He shall give to him life to those sinning not unto death; there is sin to death, not concerning it do I speak that he may beseech;
