Ezra 3:1-3

And when the seventh month had come, and the children of Israel were in the cities, the people gathered together as one man to Jerusalem. Then Jeshua the son of Jozadak and his brethren the priests, and Zerubbabel the son of Shealtiel and his brethren, 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. Though fear had come upon them because of the people of those countries, they set the altar on its bases; and they offered burnt offerings on it to the LORD, both the morning and evening burnt offerings.
