2 Timothy 2:2-5

2And the things which thou hast heard from me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.

3Suffer hardship with me, as a good soldier of Christ Jesus.

4No soldier on service entangleth himself in the affairs of this life; that he may please him who enrolled him as a soldier.

5And if also a man contend in the games, he is not crowned, except he have contended lawfully.
