Everyone who competes in the games trains with strict discipline. They do it for a crown that is perishable, but we do it for a crown that is imperishable.
KJV
And every man that striveth for the mastery is temperate in all things. Now they [do it] to obtain a corruptible crown; but we an incorruptible.
ASV
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.
