'Concerning' in the Bible

We ought to give thanks to God always concerning you, brothers, just as it is fitting, because your faith is flourishing and the love of each one of you all toward one another is increasing

Now concerning the coming of our Lord Jesus Christ and our being gathered to Him: We ask you, brothers,

But we ought to give thanks to God always concerning you, brothers [dearly] loved by the Lord, because God has chosen you [as] first fruits for salvation by the sanctification of the Spirit and faith in the truth,

As to the rest, pray ye, brethren, concerning us, that the word of the Lord may run and may be glorified, as also with you,

We have confidence in the Lord concerning you, that you are doing and will continue to do what we command.
