Demetrius II appears on the scene (1 Macc 10:67-10:69)

“In the one hundred sixty-fifth year, Demetrius son of Demetrius came from Crete to the land of his ancestors. When King Alexander heard of it, he was greatly distressed. He returned to Antioch. Demetrius appointed Apollonius the governor of Coele-syria. He assembled a large force and encamped against Jamnia.”

About 3 year later in 147 BCE, the son of Demetrius I called Demetrius II, the grandson of King Seleucus IV, came from the island of Crete. King Alexander I was upset and returned to Antioch in Syria. Demetrius II assembled a large army force in Jamnia.   He named the Philistine Apollonius the governor of this area.   Coele-syria means Hollow Syria, the area around Palestine with the sea coast town of Jamnia.
