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 one while serving as a soldier' х strateuomenos (G4754)].
The affairs ... х tais (G3588) tou (G3588) biou (G979) pragmateiais (G4230)] - mercantile, or other than military. [Zoee is the opposite of death, thanatos (G2288): and as sin caused death, where life, zoee, is, there sin is not, or ceases to be. So zoee is the nobler term in Scripture, expressing holy blessedness and eternal life; bios (G979), the present course of life: zoee, the life by which we live; bios (G979), the life which we live.]
Him who hath chosen him - the general who enlisted him. Paul himself worked at tent-making (Acts 18:3). What is prohibited is, not all secular occupation, but the becoming entangled or over-engrossed with it.
