But I did not want to do anything without your consent, so that any favor you do would not seem forced but would be voluntary. (NIV)
But it has been my wish to do nothing about it without first consulting you and getting your consent, in order that your benevolence might not seem to be the result of compulsion or of pressure but might be voluntary [on your part]. (AMP)
But without thy mind would I do nothing; that thy benefit should not be as it were of necessity, but willingly. (KJV)
