(1) The Ptolemies were a race of Egyptian kings sprung from Ptolemy Soter, who inherited that portion of the conquests of Alexander the Great. They are supposed to be alluded to in the visions of Daniel. Ptolemy I., Soter, B. C. 323-285 (Dan. 11:55And the king of the south shall be strong, and one of his princes; and he shall be strong above him, and have dominion; his dominion shall be a great dominion. (Daniel 11:5)). Ptolemy II., Philadelphus, B. C. 285-247 (Dan. 11:66And in the end of years they shall join themselves together; for the king's daughter of the south shall come to the king of the north to make an agreement: but she shall not retain the power of the arm; neither shall he stand, nor his arm: but she shall be given up, and they that brought her, and he that begat her, and he that strengthened her in these times. (Daniel 11:6)). Ptolemy III., Euergetes, B. C. 247-222 (Dan. 11:7-97But out of a branch of her roots shall one stand up in his estate, which shall come with an army, and shall enter into the fortress of the king of the north, and shall deal against them, and shall prevail: 8And shall also carry captives into Egypt their gods, with their princes, and with their precious vessels of silver and of gold; and he shall continue more years than the king of the north. 9So the king of the south shall come into his kingdom, and shall return into his own land. (Daniel 11:7‑9)). Ptolemy IV., Philopator, B. C. 222-205 (Dan. 11:10-1210But his sons shall be stirred up, and shall assemble a multitude of great forces: and one shall certainly come, and overflow, and pass through: then shall he return, and be stirred up, even to his fortress. 11And the king of the south shall be moved with choler, and shall come forth and fight with him, even with the king of the north: and he shall set forth a great multitude; but the multitude shall be given into his hand. 12And when he hath taken away the multitude, his heart shall be lifted up; and he shall cast down many ten thousands: but he shall not be strengthened by it. (Daniel 11:10‑12)). Ptolemy V., Epiphanes, B. C. 205-181 (Dan. 11:13-1713For the king of the north shall return, and shall set forth a multitude greater than the former, and shall certainly come after certain years with a great army and with much riches. 14And in those times there shall many stand up against the king of the south: also the robbers of thy people shall exalt themselves to establish the vision; but they shall fall. 15So the king of the north shall come, and cast up a mount, and take the most fenced cities: and the arms of the south shall not withstand, neither his chosen people, neither shall there be any strength to withstand. 16But he that cometh against him shall do according to his own will, and none shall stand before him: and he shall stand in the glorious land, which by his hand shall be consumed. 17He shall also set his face to enter with the strength of his whole kingdom, and upright ones with him; thus shall he do: and he shall give him the daughter of women, corrupting her: but she shall not stand on his side, neither be for him. (Daniel 11:13‑17)). Ptolemy VI., Philometor, B. C. 181-146 (Dan. 11:25-3025And he shall stir up his power and his courage against the king of the south with a great army; and the king of the south shall be stirred up to battle with a very great and mighty army; but he shall not stand: for they shall forecast devices against him. 26Yea, they that feed of the portion of his meat shall destroy him, and his army shall overflow: and many shall fall down slain. 27And both these kings' hearts shall be to do mischief, and they shall speak lies at one table; but it shall not prosper: for yet the end shall be at the time appointed. 28Then shall he return into his land with great riches; and his heart shall be against the holy covenant; and he shall do exploits, and return to his own land. 29At the time appointed he shall return, and come toward the south; but it shall not be as the former, or as the latter. 30For the ships of Chittim shall come against him: therefore he shall be grieved, and return, and have indignation against the holy covenant: so shall he do; he shall even return, and have intelligence with them that forsake the holy covenant. (Daniel 11:25‑30)). Their kingdom fell under Rome. (2) Father of Lysimachus, Greek translator of Esther (Esther 11:1).
