1 Corinthians 9:24-27

JPS_ASV_Byz(i) 24 Know ye not that they that run in a race run all, but one receiveth the prize? Even so run, that ye may attain. 25 And every man that striveth in the games exerciseth self-control in all things. Now they do it to receive a corruptible crown, but we an incorruptible. 26 I therefore so run, as not uncertainly, so fight I, as not beating the air: 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.
