ought himself also so to walk, even as he walked: "Ought" is opheilo and implies a debt (Vine 148). If one professes that he lives in fellowship with the Lord, he is duty-bound to live as Jesus lived. He owes it to the Lord to imitate His example. "To walk" is to order one’s behavior or to conduct one’s life. The little word "so" is kathos and means "according as, just as, even as" (117).
