What has happened to all your joy? I can testify that, if you could have done so, you would have torn out your eyes and given them to me. (NIV)
What has become of that blessed enjoyment and satisfaction and self-congratulation that once was yours [in what I taught you and in your regard for me]? For I bear you witness that you would have torn out your own eyes and have given them to me [to replace mine], if that were possible. (AMP)
Where is then the blessedness ye spake of? for I bear you record, that, if it had been possible, ye would have plucked out your own eyes, and have given them to me. (KJV)
