'Concerning' in the Bible

For they themselves report concerning us what kind of a reception we had from you; and how you turned to God from idols, to serve a living and true God,

and sent Timothy, our brother and God's servant in the Good News of Christ, to establish you, and to comfort you concerning your faith;

But concerning brotherly love, you have no need that one write to you. For you yourselves are taught by God to love one another,

But we don't want you to be ignorant, brothers, concerning those who have fallen asleep, so that you don't grieve like the rest, who have no hope.

But concerning the times and the seasons, brothers, you have no need that anything be written to you.
