'It is Written' in the Bible

Then Jeshua the son of Jozadak, and his brothers the priests, and Zerubbabel the son of Shealtiel, and his brothers, stood up and built the altar of the God of Israel, to offer burnt-offerings on it as it is written in the law of M

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

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