'Injured' in the Bible

Receive us: we have injured no one, we have ruined no one, we have made gain of no one.

Now I rejoice, not that ye have been grieved, but that ye have been grieved to repentance; for ye have been grieved according to God, that in nothing ye might be injured by us.

So then, if also I wrote to you, it was not for the sake of him that injured, nor for the sake of him that was injured, but for the sake of our diligent zeal for you being manifested to you before God.
