“But from a shoot from her roots one will arise.” The phrase, “from her roots,” means from the same family stock as she was from. After Ptolemy II Philadelphus (285-246 BC) died, his son, Ptolemy III Euergetes (246-221 BC; “Euergetes” means “benefactor”) came to the throne in Egypt. He was the brother of Berenice, and he amassed a large army and attacked the Seleucid kingdom to avenge his sister’s murder. The war lasted from 246-221 BC, and Ptolemy had great success. He even successfully entered and looted the Seleucid capital city, Antioch. A monument erected to him claims he subjugated Mesopotamia, Persia, Susiana, Media, and all countries as far as Bactria (John Walvoord; Daniel, pp. 333-334). He also apparently put Laodice to death.
Ptolemy carried the Seleucid gods into Egypt as a sign of their total defeat. This was often done by victorious nations (see commentary on Dan. 11:8).
