Ezra 4:1-6

Now when the adversaries of Judah and Benjamin heard that the children of the captivity builded the temple unto the LORD God of Israel; then they came to Zerubbabel, and to the chief of the fathers, and said unto them, Let us build with you: for we seek your God, as ye do; and we do sacrifice unto him since the days of Esarhaddon king of Assur, which brought us up hither. But Zerubbabel, and Jeshua, and the rest of the chief of the fathers of Israel, said unto them, Ye have nothing to do with us to build an house unto our God; but we ourselves together will build unto the LORD God of Israel, as king Cyrus the king of Persia hath commanded us. Then the people of the land weakened the hands of the people of Judah, and troubled them in building, and hired counsellors against them, to frustrate their purpose, all the days of Cyrus king of Persia, even until the reign of Darius king of Persia. And in the reign of Ahasuerus, in the beginning of his reign, wrote they unto him an accusation against the inhabitants of Judah and Jerusalem.
