'Concerning' in the Bible

He came to the men of Succoth and said, “Behold Zebah and Zalmunna, concerning whom you taunted me, saying, ‘Are the hands of Zebah and Zalmunna already in your hand, that we should give bread to your men who are weary?’”

Then the sons of Israel said, “Who is there among all the tribes of Israel who did not come up in the assembly to the Lord?” For they had taken a great oath concerning him who did not come up to the Lord at Mizpah, saying, “He shall surely be put to death.”
