And so I will draw a dotted line from Achaemenes to Cyrus. And Cyrus then goes on, so he conquers the Median Empire. Then he goes on to conquer several of the major empires of that time. In the mid 540s BCE, so we are right around there, he conquers the Lydian Empire, right over there, which is on the western half of the Anatolian Peninsula in modern-day Turkey. And then he sets his sight on the Neo-Babylonian Empire. And in 539, he's able to conquer the Neo-Babylonian Empire. And from a biblical perspective, that's relevant, because when he takes Babylon, he frees the Jews from the Babylonian captivity and he resettles them in Jerusalem.
