'Concerning' in the Bible

You have also set up prophets to proclaim in Jerusalem concerning you, saying, '[There is] a king in Judah.' And now it will be proclaimed to the king according to these words. Now, come and we will plan together."

For [there was] a command of the king concerning them and a regulation concerning the singers, required {day by day}.

And Pethahiah son of Meshezabel, from the descendants of Zerah the son of Judah, [was] at the hand of the king in all matters concerning the people.

Remember me, my God, concerning this, and do not wipe out my loyal acts which I have done in the house of my God and in his service.
