A great Grecian king will conquer the Persian empire but would have his kingdom divided four ways after his death. The Greek empire would not go to the Great kings’s heirs.
Fulfilled in 330 BC when Alexander the Great defeats Persia and 281 BC after the Greek generals who succeed Alexander reach an agreement after years of war to split the kingdom four ways. The name “Alexander” or “Alexander the Great,” referring to the Macedonian king, never appears in the Bible. However, the prophets Daniel and Zechariah wrote prophecies concerning Greece and Alexander’s Macedonian Empire. The non-eschatological prophecies in Daniel have proved so reliable that some critics have tried to post-date his writing, even though copious literary, historical and biblical factors point to a date of writing in the sixth century B.C. (see the third paragraph of this article). Zechariah, writing sometime between 520 and 470 B.C., was also well before Alexander’s rise to power.
