'Concerning' in the Bible

Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh;

Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.

Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:

As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes.

For your obedience is come abroad unto all men. I am glad therefore on your behalf: but yet I would have you wise unto that which is good, and simple concerning evil.
