'Instructions' in the Bible

When the builders established the Lord's temple, the priests, ceremonially attired and with their clarions, and the Levites (the sons of Asaph) with their cymbals, stood to praise the Lord according to the instructions left by King David of Israel.

Then Tattenai governor of Trans-Euphrates, Shethar-Bozenai, and their colleagues acted accordingly -- with precision, just as Darius the king had given instructions.
