'Concerning' in the Bible

I will teach you concerning the hand of God; what is with the Almighty will I not conceal.

His thundering declareth concerning him; the cattle even, concerning its coming.

And all his brethren, and all his sisters, and all they that had been of his acquaintance before, came to him, and they ate bread with him in his house, and they condoled with him, and comforted him concerning all the evil that Jehovah had brought upon him; and every one gave him a piece of money, and every one a golden ring.
