'It is Written' in the Bible

And rise doth Jeshua son of Jozadak, and his brethren the priests, and Zerubbabel son of Shealtiel, and his brethren, and they build the altar of the God of Israel, to cause to ascend upon it burnt-offerings, as it is written in the law of Moses, the man of God.

And they make the feast of the booths as it is written, and the burnt-offering of the day daily in number according to the ordinance, the matter of a day in its day;

and they have established the priests in their divisions, and the Levites in their courses, over the service of God that is in Jerusalem, as it is written in the book of Moses.
