Adam Clarke on Daniel 11:14

Many stand up against the king of the south - Antiochus, and Philip king of Macedon, united together to overrun Egypt.

Also the robbers of thy people - The Jews, who revolted from their religion, and joined Ptolemy, under Scopas: -

Shall exalt themselves to establish the vision - That is, to build a temple like that of Jerusalem, in Egypt, hoping thereby to fulfil a prediction of Isaiah, Isa 30:18-25, which seemed to intimate that the Jews and the Egyptians should be one people. They now revolted from Ptolemy, and joined Antiochus; and this was the means of contributing greatly to the accomplishment of prophecies that foretold the calamities that should fall upon the Jews.

But they shall fall - For Scopas came with a great army from Ptolemy; and, while Antiochus was engaged in other parts, reduced Coelesyria and Palestine, subdued the Jews, placed guards on the coasts of Jerusalem, and returned with great spoils to Egypt.
