'It is Written' in the Bible

And Jeshua the son of Jozadak stood up, and his brothers the priests, and Zerubbabel the son of Shealtiel, and his brothers. And they built the altar of the God of Israel in order to offer burnt offerings on it, as it is written in the Law of Moses the man of God.

And they kept the feast of tabernacles, as it is written, and offered the daily burnt offerings by number, according to the custom, as the duty of every day required.

And they set the priests in their sections, and the Levites in their divisions, for the service of God which is at Jerusalem, as it is written in the book of Moses.
