I also will choose their delusions, and will bring their fears upon them; because when I called, none did answer; when I spoke, they did not hear: but they did evil before mine eyes, and chose that in which I delighted not.

In the title verse the LORD is speaking of this time, now when mass delusion and its resulting fear have taken hold of all the world. The latter part of His statement tells of His rejected warning: advising that the mental state of all, including His people, was such that they had become ignorant of the magnitude of the evil already manipulating and controlling all humanity.

He begins the chapter, Isaiah 66, by declaring Himself separate from and sovereign over these events. He says He will look to those who are poor and of a contrite spirit, who tremble at His word. This is contrasted against those that are blessing idols and who delight in their abominations, of whom He then speaks in the title verse.

Isaiah 26
1 In that day shall this song be sung in the land of Judah; We have a strong city; salvation will God appoint for walls and bulwarks.
2 Open you the gates, that the righteous nation which keeps the truth may enter in.
3 You will keep him in perfect peace, whose mind is stayed on you: because he trusts in you.
4 Trust you in the LORD forever: for in the LORD Jehovah is everlasting strength:
5 For he brings down them that dwell on high; the lofty city, he lays it low; he lays it low, even to the ground; he brings it even to the dust.
6 The foot shall tread it down, even the feet of the poor, and the steps of the needy.
7 The way of the just is uprightness: you, most upright, do weigh the path of the just.
8 Yea, in the way of your judgments, O LORD, have we waited for you; the desire of our soul is to your name, and to the remembrance of you.
9 With my soul have I desired you in the night; yea, with my spirit within me will I seek you early: for when your judgments are in the earth, the inhabitants of the world will learn righteousness.
10 Let favor be shown to the wicked, yet will he not learn righteousness: in the land of uprightness will he deal unjustly, and will not behold the majesty of the LORD.
11 LORD, when your hand is lifted up, they will not see: but they shall see, and be ashamed for their envy at the people; yea, the fire of your enemies shall devour them.
12 LORD, you will ordain peace for us: for you also have wrought all our works in us.
13 O LORD our God, other lords beside you have had dominion over us: but by you only will we make mention of your name.
14 They are dead, they shall not live; they are deceased, they shall not rise: therefore have you visited and destroyed them, and made all their memory to perish.
15 You have increased the nation, O LORD, you have increased the nation: you are glorified: you had removed it far unto all the ends of the earth.
16 LORD, in trouble have they visited you, they poured out a prayer when your chastening was upon them.
17 Like as a woman with child, that draws near the time of her delivery, is in pain, and cries out in her pangs; so have we been in your sight, O LORD.
18 We have been with child, we have been in pain, we have as it were brought forth wind [instead of new birth they brought forth gas]; we have not wrought any deliverance in the earth; neither have the inhabitants of the world fallen [into the birth canal].
19 Your dead men shall live, together with my dead body shall they arise. Awake and sing, you that dwell in dust: for your dew is as the dew of herbs, and the earth shall cast out the dead.
20 Come, my people, enter into your chambers, and shut your doors about you: hide yourselves as it were for a little moment, until the indignation be over-past.
21 For, behold, the LORD comes out of his place to punish the inhabitants of the earth for their iniquity: the earth also shall disclose her blood, and shall no more cover her slain.
