1 Chronicles 28:21

And. Behold, the courses of the priests and the Levites, who were surely also represented in the assembly on that day, 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, the skilled artisan as well as the ordinary craftsman or workman; also the princes and all the people will be wholly at thy commandment; of this David was convinced from his acquaintance with them all and from the cheerful loyalty they had shown him for more than thirty years, except in the matter of the rebellion of Absalom. It is well-pleasing to God and serves as a great encouragement to His servants if all men, great and small, stand together for the purpose of building His kingdom on earth, no matter what special business may be at hand.
