If you look at every usage in scripture it is being used to disagree with or correct something that has been said.

This source too relies on contributors. If we are to take Strong's Concordance we have to first admit that it is not infallible and that it is based upon the King James translation which itself is flawed.
Since you seem so intent on appealing to authority, why don't you look to what the Early Church Fathers had to say on the subject, those who were either students of the Apostles or were no more than a generation or two removed from those who were?
