“For though we walk in the flesh, we do not war after the flesh:”
King James Version (KJV)
10:3 Though we walk in the flesh - In mortal bodies, and, consequently, are not free from human weakness. Yet we do not war - Against the world and the devil. After the flesh - By any carnal or worldly methods. Though the apostle here, and in several other parts of this epistle, speaks in the plural number, for the sake of modesty and decency, yet he principally means himself. On him were these reflections thrown, and it is his own authority which he is vindicating.
2Co 10:3 We walk in the flesh. He is in the body, but though in the flesh does not use fleshly weapons in his warfare.
