2 Timothy 2:5 in the King James Version
And if a man also strive for masteries, yet is he not crowned, except he strive lawfully.
Context
4 No soldier on duty entangles himself in the affairs of life, that he may please him who enrolled him as a soldier.
5 Also, if anyone competes in athletics, he isn’t crowned unless he has competed by the rules.
6 The farmer who labors must be the first to get a share of the crops.
