'Concerning' in the Bible

And he came unto the men of Succoth, and said, Behold Zebah and Zalmunna, concerning whom ye did taunt me, saying, Are the hands of Zebah and Zalmunna now in thy hand, that we should give bread unto thy men that are weary?

And the children of Israel said, Who is there among all the tribes of Israel that came not up in the assembly unto Jehovah? For they had made a great oath concerning him that came not up unto Jehovah to Mizpah, saying, He shall surely be put to death.
