1 Chronicles 28:20-21

And David said to Solomon his son, Be strong and of good courage, and do it: fear not, nor be dismayed: for the LORD God, even my God, will be with thee; he will not fail thee, nor forsake thee, until thou hast finished all the work for the service of the house of the LORD. And, behold, the courses of the priests and the Levites, even they shall be with thee for all the service of the house of God: and there shall be with thee for all manner of workmanship every willing skilful man, for any manner of service: also the princes and all the people will be wholly at thy commandment.
