'Orders' in the Bible

As his father David had decreed, Solomon appointed the divisions of the priests to do their assigned tasks, the Levitical orders to lead worship and help the priests with their daily tasks, and the divisions of the gatekeepers to serve at their assigned gates. This was what David the man of God had ordered.

They did not neglect any detail of the king's orders pertaining to the priests, Levites, and treasuries.

The following Levites prepared to carry out the king's orders: From the Kohathites: Mahath son of Amasai and Joel son of Azariah; from the Merarites: Kish son of Abdi and Azariah son of Jehallelel; from the Gershonites: Joah son of Zimmah and Eden son of Joah;

King Hezekiah stationed the Levites in the Lord's temple with cymbals and stringed instruments, just as David, Gad the king's prophet, and Nathan the prophet had ordered. (The Lord had actually given these orders through his prophets.)
