18 They know nothing, they understand nothing; their eyes are plastered over so they cannot see, and their minds closed so they cannot understand.

Read Isaiah 44:18 Using Other Translations

They have not known nor understood: for he hath shut their eyes, that they cannot see; and their hearts, that they cannot understand.
They know not, nor do they discern, for he has shut their eyes, so that they cannot see, and their hearts, so that they cannot understand.
Such stupidity and ignorance! Their eyes are closed, and they cannot see. Their minds are shut, and they cannot think.
