1 Corinthians 9:25-27

New Revised Standard Version Catholic Edition

²⁵ Athletes exercise self-control in all things; they do it to receive a perishable wreath, but we an imperishable one. ²⁶ So I do not run aimlessly, nor do I box as though beating the air; ²⁷ but I punish my body and enslave it, so that after proclaiming to others I myself should not be disqualified.
