Ezra 4:2-3

2 they approached Zerubbabel and the heads of families and said to them, "Let us build with you, for we worship your God as you do, and we have been sacrificing to him ever since the days of King Esar-haddon of Assyria who brought us here."
3 But Zerubbabel, Jeshua, and the rest of the heads of families in Israel said to them, "You shall have no part with us in building a house to our God; but we alone will build to the Lord, the God of Israel, as King Cyrus of Persia has commanded us."
