1 Corinthians 9:26-27

New American Standard Bible

²⁶ Therefore I ^(A)run in such a way as not to run aimlessly; I box in such a way, as ^[a]to avoid ^(B)hitting air; ²⁷ but I strictly discipline ^(C)my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified.
