And he shall stir up his power and his courage against the king of the south with a great army; and the king of the south shall be stirred up to battle with a very great and mighty army; but he shall not stand: for they shall forecast devices against him. He shall stir up his power - Antiochus marched against Ptolemy, the king of the south, (Egypt), with a great army; and the Egyptian generals had raised a mighty force.
Stirred up to battle - The two armies met between Pelusium and Mount Casius; but he (the king of the south) could not stand - the Egyptian army was defeated. The next campaign he had greater success; he routed the Egyptian army, took Memphis, and made himself master of all Egypt, except Alexandria, see 1 Maccabees 1:16-19. And all these advantages he gained by forecasting devices; probably by corrupting his ministers and captains. Ptolemy Macron gave up Cyprus to Antiochus; and the Alexandrians were led to renounce their allegiance to Ptolemy Philometer, and took Euergetes, or Physcon his younger brother, and made him king in his stead. All this was doubtless by the corruptions of Antiochus. See below.
