1 Chronicles 28:19-21

19“All this,” said David, “the Lord made me understand in writing, by His hand upon me, all the works of these plans.”

20And David said to his son Solomon, “Be strong and of good courage, and do it; do not fear nor be dismayed, for the Lord God—my God—will be with you. He will not leave you nor forsake you, until you have finished all the work for the service of the house of the Lord.

21Here are the divisions of the priests and the Levites for all the service of the house of God; and every willing craftsman will be with you for all manner of workmanship, for every kind of service; also the leaders and all the people will be completely at your command.”
