The moment
After Cyrus of Persia took Babylon in 539 BCE, a foundation inscription in his name was composed in Akkadian by the priests of Marduk. In it Marduk searches for a righteous king, chooses Cyrus, condemns the last Babylonian king Nabonidus, and lets Cyrus enter Babylon without a battle; Cyrus then returns the gods and their peoples to the sanctuaries from which they had been removed. The text does not mention Judah, though the Bible records Cyrus permitting the exiles to go home.
People: Cyrus the Great, Nabonidus
