The Temple was rebuilt, but the real crisis was internal. Josephus records that when the returnees from Babylon laid the foundation, the Samaritans—descendants of foreigners whom Assyria had planted in the land—came asking to help build. Zerubbabel and the High Priest Jeshua refused them. The Samaritans retaliated by writing letters to the Persian court, warning that Jerusalem had a history of rebellion. It worked. For nine years, the building was halted.
When the prophets Haggai and Zechariah finally pushed the Jews to resume building, the regional governors sent another complaint to King Darius. But this time, Darius searched the royal archives and found Cyrus's original decree. He ordered the construction to continue and threatened to hang anyone who interfered. The Temple was finished in seven years.
Then came Ezra. A priest and scribe who had remained in Babylon, he arrived in Jerusalem with a royal letter from King Xerxes granting him authority over all Jewish religious affairs. What he found horrified him. The people—including priests and Levites—had married foreign wives. Ezra tore his garments and pulled out his own hair. He fell on his face before God and prayed with such anguish that a crowd gathered and wept with him.
Ezra demanded that every man who had married a foreign woman divorce her. It was brutal. Many resisted. But Ezra gathered the entire nation at the Temple and read the Torah aloud from dawn until midday. When the people heard the words, they wept—because they recognized how far they had fallen. After him, Nehemiah arrived and rebuilt the walls of Jerusalem in just two years and four months, despite constant threats from surrounding nations. He built the people houses at his own expense and filled the city with residents. The return from exile was not a single event but a generation-long struggle.
