1 Chronicles 9:22

22. Whom David and Samuel the seer did ordain This statement adds further to the dignity and honour of the office of the porters. But Samuel the seer was dead long before David reorganized and arranged the various departments of the sanctuary service, and so this passage is to be understood of Samuel’s indirect assistance in the matter, either by planning and advising with David on the subject during his lifetime, or, as is more probable, by actually taking measures to organize and arrange the Levites for service during the reign of Saul. “The mention of Samuel after David,” says Keil, “has not a chronological signification, but David is named first on account of his connexion with the matter in hand, for the thorough reorganization of the worship, and the classification of the persons engaged in carrying it on, originated with David. For these arrangements of David, however, Samuel had prepared the way in his struggle for the restoration of the theocracy, and of the worship which had fallen into desuetude under Eli and his profligate sons. To do this in any measure he must have, without doubt, ordained trustworthy men to the individual offices, and thus have prepared the way for King David.”
