Isaiah 33:16

he shall dwell on high, in places inaccessible to the foe, his place of defense shall be the munitions of rocks, the fastnesses of the mountains, where he dwells under the protection of Jehovah; bread shall be given him; his waters shall be sure, he will have both food and drink in rich abundance. Thus the prophet draws a sketch of one who, under the guidance and by the power of Jehovah, does not need to fear the judgment of wrath which will came upon those who delight in wickedness. The description causes the prophet to forget the sordid present and to look forward to the time when the congregation of the Lord would consist entirely of such desirable members.
