Adam Clarke on Daniel 11:10

But his sons shall be stirred up - That is, the sons of Callinicus, who were Seleucus Ceraunus and Antiochus, afterwards called the Great.

Shall assemble a multitude - Seleucus Ceraunus did assemble a multitude of forces in order to recover his father's dominions; but, not having money to pay them, they became mutinous, and he was poisoned by two of his own generals. His brother Antiochus was then proclaimed king; so that one only of the sons did certainly come, and overflow, and pass through; he retook Seleucia, and regained Syria. He then returned, and overcame Nicolaus the Egyptian general; and seemed disposed to invade Egypt, as he came even to his fortress, to the frontiers of Egypt.
