Ehud came to him; and he was sitting by himself alone in the cool upper room. Ehud said, I have a message from God to you. He arose out of his seat.
      [3.] He contrived how to be alone with him, which he might the more easily be now that he had not only made himself known to him, but ingratiated himself by the present, and the compliments which perhaps, on this occasion, he had passed upon him. Observe, how he laid his plot. First, He concealed his design even from his own attendants, brought them part of the way, and then ordered them to go forward towards home, while he himself, as if he had forgotten something behind him, went back to the king of Moab's court, Judges 3:18; Judges 3:18. There needed but one hand to do the execution; had more been engaged they could not so safely have kept counsel, nor so easily have made an escape. Secondly, He returned from the quarries by Gilgal (Judges 3:19; Judges 3:19), from the graven images (so it is in the margin) which were with Gilgal, set up perhaps by the Moabites with the twelve stones which Joshua had set up there. Some suggest that the sight of these idols stirred up in him such an indignation against the king of Moab as put him upon the execution of that design which otherwise he had thought to let fall for the present. Or, perhaps, he came so far as to these images, that, telling from what place he returned, the king of Moab might be the more apt to believe he had a message from God. Thirdly, He begged a private audience, and obtained it in a withdrawing-room, here called a summer parlour. He told the king he had a secret errand to him, who thereupon ordered all his attendants to withdraw, Judges 3:19; Judges 3:19. Whether he expected to receive some private instructions from an oracle, or some private informations concerning the present state of Israel, as if Ehud would betray his country, it was a very unwise thing for him to be all alone with a stronger and one whom he had reason to look upon as an enemy; but those that are marked for ruin are infatuated, and their hearts hid from understanding; God deprives them of discretion.
