'Concerned' in the Bible

"Thus the Lord has done for me in the days in which he has concerned himself with [me], to take away my disgrace among people."

So do not be overly concerned about what you will eat and what you will drink, and do not worry about such things.

because it is the unbelievers who are concerned about all these things. Surely your Father knows that you need them!

Instead, be concerned about his kingdom, and these things will be provided for you as well.

"Be concerned about yourselves! If your brother sins, rebuke him, and if he repents, forgive him.
