Ezra 4:2-3

2they came to Zerubbabel and to the heads of the families and said, “Let us help you build because, like you, we seek your God and have been sacrificing to him since the time of Esarhaddon king of Assyria, who brought us here.” 3But Zerubbabel, Joshua and the rest of the heads of the families of Israel answered, “You have no part with us in building a temple to our God. We alone will build it for the Lord, the God of Israel, as King Cyrus, the king of Persia, commanded us.”
