Ptolemy Iii Euergetes in Wikipedia
Ptolemy III Euergetes, (Greek: Πτολεμαῖος Εὐεργέτης, Ptolemaĩos Euergétēs, reigned 246 BC–222 BC) was the third ruler of the Ptolemaic dynasty in Egypt.
Euergetes ("Benefactor") was the eldest son of Ptolemy II Philadelphus and his first wife, Arsinoe I, and came to power in 246 BC upon the death of his father. He married Berenice of Cyrene in the year corresponding to 244/243 BC; and their children were:
* Arsinoe III, born in ca 246/245 BC. She later married her brother Ptolemy IV
* Ptolemy IV Philopator, born ca 244 BC
* Possibly Lysimachus. The name of the son is not known, but he is said to have been born in ca 243 BC.
* Alexander, born in c. 242 BC 
* Magas, probably born in ca 241 BC. Scalded to death in his bath by Theogos or Theodotus, at the orders of Ptolemy IV. 
* Berenice, probably born in ca 239 BC and died a year later. 
Ptolemy III Euergetes was responsible for the first known example of a series of decrees published as bilingual inscriptions on massive stone blocks in three writing systems. Ptolemy III's stone stela is the Canopus Stone of 238 BC. Other well-known examples are the Memphis Stele (Memphis Stone), bearing the Decree of Memphis, about 218 BC, passed by his son, Ptolemy IV, and the famous Rosetta Stone erected by Ptolemy Epiphanes, his grandson, in 196 BC.
Ptolemy III's stone contains decrees about priestly orders, and is a memorial for his daughter Berenice. But two of its 26 lines of hieroglyphs decree the use of a leap day added to the Egyptian calendar of 365 days, and the associated changes in festivals.
He is also credited with the foundation of the Serapeum.
War with Seleucids
Due to a falling out at the Seleucid court, his eldest sister Berenice Phernophorus was murdered along with her infant son. In response Ptolemy III invaded Syria. During this war, the Third Syrian War, he occupied Antioch and even reached Babylon.
This war is cryptically alluded to in Daniel XI 7-9.
