“But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;”
King James Version (KJV)
3:14 From whom - Even from me a teacher approved of God.
2Ti 3:14 Continue thou. Refusing to heed the evil men, continue in the truth. Knowing from whom thou hast learned [them]. Of pious parents first (2Ti 1:5), but more especially of Paul (Ac 16:1).
