27 No, I strike a blow to my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.

27 But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified.

27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.

27 I discipline my body like an athlete, training it to do what it should. Otherwise, I fear that after preaching to others I myself might be disqualified.

27 But I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified.

27 I treat my body hard and make it my slave so that I myself will not be disqualified after I have preached to others.

27 but I buffet my body, and bring it into bondage: lest by any means, after that I have preached to others, I myself should be rejected.

27 But I buffet my body, and lead it captive, lest after having preached to others I should be myself rejected.

27 Rather, I toughen my body with punches and make it my slave so that I will not be disqualified after I have spread the Good News to others. 

27 Instead, I discipline my body and bring it under strict control, so that after preaching to others, I myself will not be disqualified.

27 but I punish my body and enslave it, so that after proclaiming to others I myself should not be disqualified.

27 But I discipline my body and subjugate it, lest somehow after preaching to others, I myself should become disqualified.

27 No, I train my body and bring it under control. Then after I have preached to others, I myself will not break the rules and fail to win the prize.
