One told David Or, David told; that is, being informed that Ahithophel was among the conspirators, he mentioned it to his friends, to excite them to join with him in the following prayer against him. Turn the counsel of Ahithophel into foolishness. Either infatuate him, that he may give foolish counsel; or let his counsel be contemned and rejected as foolish; or let it miscarry in the execution. Thus David's constant recourse, in all his dangers and difficulties, was unto God by prayer.
