'Concerning' in the Bible

And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this sore travail hath God given to the sons of man to be exercised therewith.

I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.

Say not thou, What is the cause that the former days were better than these? for thou dost not inquire wisely concerning this.
