'Concerned' in the Bible

Look, I am stirring up the Medes to attack them; they are not concerned about silver, nor are they interested in gold.

Why do you say, Jacob, Why do you say, Israel, "The Lord is not aware of what is happening to me, My God is not concerned with my vindication"?

He was taken by restraint of justice, and who concerned himself with his generation? For he was cut off from the land of [the] living; he [received a] blow because of the transgression of my people.

"As far as I am concerned, this is like in Noah's time, when I vowed that the waters of Noah's flood would never again cover the earth. In the same way I have vowed that I will not be angry at you or shout at you.

No one is concerned about justice; no one sets forth his case truthfully. They depend on false words and tell lies; they conceive of oppression and give birth to sin.
