Ezra 3:1-3 NIV
When the seventh month came and the Israelites had settled in their towns, the people assembled together as one in Jerusalem. Then Joshua son of Jozadak and his fellow priests and Zerubbabel son of Shealtiel and his associates began to build the altar of the God of Israel to sacrifice burnt offerings on it, in accordance with what is written in the Law of Moses the man of God. Despite their fear of the peoples around them, they built the altar on its foundation and sacrificed burnt offerings on it to the LORD, both the morning and evening sacrifices.
