'Instructions' in the Bible

Then Jeshua the son of Jozadak and his brothers the priests, and Zerubbabel the son of Shealtiel and his brothers arose, and they 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.

“Artaxerxes, king of kings, to Ezra the priest, the scribe of the Law of the God of heaven, perfect peace (greetings). And now

“And I, Artaxerxes the king, issue a decree to all the treasurers in the provinces west of the [Euphrates] River, that whatever Ezra the priest, the scribe of the Law of the God of heaven, may require of you, it shall be done diligently and at once—

“You, Ezra, are to appoint magistrates and judges in accordance with the wisdom and instruction of your God which is in your hand, so that they may judge all the people who are in the province west of the [Euphrates] River; appoint those who know the laws of your God; and you may teach anyone who does not know them.
