12. when he hath taken away--that is, subdued "the multitude" of Antiochus.
      heart . . . lifted up--instead of following up his victory by making himself master of the whole of Syria, as he might, he made peace with Antiochus, and gave himself up to licentiousness [POLYBIUS, 87; JUSTIN, 30.4], and profaned the temple of God by entering the holy place [GROTIUS].
      not be strengthened by it--He shall lose the power gained by his victory through his luxurious indolence.
