Ezra 4:1-2

1When the enemies of Judah and Benjamin heard that the people who returned from exile were building a temple for the Lord God of Israel,

2they approached Zerubbabel and the heads of the families. They told them, “We want to help you build because we worship the same God you worship. We have been sacrificing to him  since the time of King Esarhaddon of Assyria, who brought us here.”
