Adam Clarke on Daniel 11:7

But out of a branch of her roots - A branch from the same root from which she sprang. This was Ptolemy Euergetes, her brother, who, to avenge his sister's death, marched with a great army against Seleucus Callinicus, took some of his best places, indeed all Asia, from Mount Taurus to India, and returned to Egypt with an immense booty, forty thousand talents of silver, precious vessels, and images of their gods two thousand five hundred, without Callinicus daring to offer him battle. I can but touch on these historic facts, for fear of extending these notes to an immoderate length.
