Everyone has heard about your obedience, so I rejoice because of you; but I want you to be wise about what is good, and innocent about what is evil. (NIV)
For while your loyalty and obedience is known to all, so that I rejoice over you, I would have you well versed and wise as to what is good and innocent and guileless as to what is evil. (AMP)
For your obedience is come abroad unto all men. I am glad therefore on your behalf: but yet I would have you wise unto that which is good, and simple concerning evil. (KJV)
