JST, Isaiah 42:19–23. Compare Isaiah 42:19–22

The Lord sends His servant to teach those who have chosen not to see or hear the truth; those who listen and obey will be made perfect.

19 For I will send my servant unto you who are blind; yea, a messenger to open the eyes of the blind, and unstop the ears of the deaf;

20 And they shall be made perfect notwithstanding their blindness, if they will hearken unto the messenger, the Lord’s servant.

21 Thou art a people, seeing many things, but thou observest not; opening the ears to hear, but thou hearest not.

22 The Lord is not well pleased with such a people, but for his righteousness’ sake he will magnify the law and make it honorable.

23 Thou art a people robbed and spoiled; thine enemies, all of them, have snared thee in holes, and they have hid thee in prison houses; they have taken thee for a prey, and none delivereth; for a spoil, and none saith, Restore.
