Ezra 3:1-6

Now when the seventh month came, and the sons of Israel were in the cities, the people gathered together as one man to Jerusalem. Then Jeshua the son of Jozadak and his brothers the priests, and Zerubbabel the son of Shealtiel and his brothers arose and built the altar of the God of Israel to offer burnt offerings on it, as it is written in the law of Moses, the man of God. So they set up the altar on its foundation, for they were terrified because of the peoples of the lands; and they offered burnt offerings on it to the LORD, burnt offerings morning and evening. They celebrated the Feast of Booths, as it is written, and offered the fixed number of burnt offerings daily, according to the ordinance, as each day required; and afterward there was a continual burnt offering, also for the new moons and for all the fixed festivals of the LORD that were consecrated, and from everyone who offered a freewill offering to the LORD. From the first day of the seventh month they began to offer burnt offerings to the LORD, but the foundation of the temple of the LORD had not been laid.
