What did Cyrus, king of Persia, decree for the Jews after 70 years?
After the 70 years, Cyrus, king of Persia, decreed that the Jews could return to Jerusalem, rebuild the temple, restore temple worship, and reestablish their national entity under his sovereignty. Ezra 1:1 notes this occurred in his first year so the word of the LORD spoken by Jeremiah might be fulfilled.
Les explains that the southern kingdom of Judah was overrun by Nebuchadnezzar coming out from Babylon, and the Jews ended up in captivity for 70 years. At the end of that period, as mentioned from Chronicles, Cyrus, the king of Persia, made a decree that the Jews could go back to Jerusalem, rebuild the temple, reestablish temple worship, and reestablish their national entity under his sovereignty. Ezra 1:1 places this in the first year of Cyrus, king of Persia, so that the word of the LORD by the mouth of Jeremiah might be fulfilled, spoken years before it happened.
