And what can David say more unto thee? for thou, Lord GOD, knowest thy servant.
What can David say more unto thee - i:e., my obligations are infinitely greater than I can express; and then, "thou, Lord, knowest thy servant," must refer to the deep, unspeakable feelings of his ravished heart. But by reference to the parallel passage (1 Chronicles 17:17), this is spoken rather as a prayer, intimating that David could neither ask nor desire anything greater than what had been now conferred; and therefore he would leave all his wants to be supplied by his gracious 'Lord, who knew his servant.'
