Ezra 3:1-6 ESV

When the seventh month came, and the children of Israel were in the towns, the people gathered as one man to Jerusalem. Then arose Jeshua the son of Jozadak, with his fellow priests, and Zerubbabel the son of Shealtiel with his kinsmen, and they 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. They set the altar in its place, for fear was on them because of the peoples of the lands, and they offered burnt offerings on it to the LORD, burnt offerings morning and evening. And they kept the Feast of Booths, as it is written, and offered the daily burnt offerings by number according to the rule, as each day required, and after that the regular burnt offerings, the offerings at the new moon and at all the appointed feasts of the LORD, and the offerings of everyone who made 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 was not yet laid.
