2 Timothy 2:4
A soldier refrains from entangling himself in civilian affairs, in order to please the one who enlisted him.
Berean Standard Bible
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.
No soldier on duty entangles himself in the affairs of life, that he may please him who enrolled him as a soldier.
