And he came to the ram that had two horns, which I had seen standing before the river, and ran unto him in the fury of his power. The differences of the Septuagint from the received text are slight here.
Oobal is still translated πύλη; it renders, "fury of his rage" rather than "fury of his power." The Massoretic, as the less obvious collocation, is the better reading. Theodotion and the Peshitta leave oobal untranslated.
The latter omits the last clause of the Massoretic. In the Hebrew the ram is called Baal-karnayeem, "lord of two horns." Alexander's war against Persia was one of simple aggression.
