Isaiah 44:18 in the King James Version
They have not known nor understood: for he hath shut their eyes, that they cannot see; and their hearts, that they cannot understand.
Context
17 The rest of it he makes into a god, even his engraved image. He bows down to it and worships, and prays to it, and says, “Deliver me, for you are my god!”
18 They don’t know, neither do they consider, for he has shut their eyes, that they can’t see, and their hearts, that they can’t understand.
19 No one thinks, neither is there knowledge nor understanding to say, “I have burned part of it in the fire. Yes, I have also baked bread on its coals. I have roasted meat and eaten it. Shall I make the rest of it into an abomination? Shall I bow down to a tree trunk?”
