“No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier.”
King James Version (KJV)
2:4 No man that warreth entangleth himself - Any more than is unavoidable. In the affairs of this life - With worldly business or cares. That - Minding war only, he may please his captain. In this and the next verse there is a plain allusion to the Roman law of arms, and to that of the Grecian games. According to the former, no soldier was to engage in any civil employment; according to the latter, none could be crowned as conqueror, who did not keep strictly to the rules of the game.
2Ti 2:4 No man that warreth entangleth himself with the affairs of [this] life. The soldier to do good service must devote himself entirely to the soldier's life, giving up worldly affairs. So the soldier, like Timothy, engaged as a minister, should have no other business.
