Ezra 3:1-3

And when the seventh month was come, and the children of Israel were in the cities, the people gathered themselves together as one man to Jerusalem. Then stood up Jeshua the son of Jozadak, and his brethren the priests, and Zerubbabel the son of Shealtiel, and his brethren, and builded the altar of the God of Israel, to offer burnt-offerings thereon, as it is written in the law of Moses the man of God. And they set the altar upon its base; for fear was upon them because of the peoples of the countries: and they offered burnt-offerings thereon unto Jehovah, even burnt-offerings morning and evening.
