'Concerning' in the Bible

For we don't desire to have you uninformed, brothers, concerning our affliction which happened to us in Asia, that we were weighed down exceedingly, beyond our power, so much that we despaired even of life.

I rejoice that in everything I am confident concerning you.

We are avoiding this, that any man should blame us concerning this abundance which is administered by us.

It is indeed unnecessary for me to write to you concerning the service to the saints,

For though I should boast somewhat abundantly concerning our authority, (which the Lord gave for building you up, and not for casting you down) I will not be disappointed,

Concerning this thing, I begged the Lord three times that it might depart from me.
