1 Corinthians 9:26-27

Expanded Bible

²⁶ So I do not run ·without a goal [aimlessly]. I fight like a boxer who is hitting something—not just the air. ²⁷ I ·treat my body hard [discipline/subdue/pummel my body] and ·make it my slave [subdue it] so that I myself will not be disqualified after I have preached to others.
