Charles Ellicott Commentary Daniel 11:15

"So the king of the north shall come, and cast up a mound, and take a well-fortified city: and the forces of the south shall not stand, neither his chosen people, neither shall there be any strength to stand." — Daniel 11:15 (ASV)

The king of the north.— This prince attacks the fortress of his rival, who is unable to resist him. Here it is supposed that the allusion is to the capture of Sidon by Antiochus the Great. The troops of Ptolemy under Scopas had acquired possession of Jerusalem and of various portions of Syria during the absence of Antiochus. Scopas and the Egyptian troops under him fled to Sidon, where they were forced by famine to surrender to the Syrians (B.C. 198).

The arms of the south.—Compare to Daniel 11:31. The phrase means the armed force of the south.
