Isaiah 29:10

10 For the LORD has extended upon you the spirit of deep sleep and has closed your eyes: the prophets and your rulers, he has covered the seers with sleep.

Isaiah 29:10 In-Context

8 It shall even be as he who dreams that he is hungry, and in his dream, he eats; but when he awakes, his soul is empty; and as he who dreams that he is thirsty, and, in his dream, he drinks; but he awakes, and, behold, he is faint, and his soul is still thirsty: so shall the multitude of all the Gentiles be, that shall fight against Mount Zion.
9 Become ye dumb, and make others dumb; become ye blind, and blind others: they are drunken, but not with wine; they stagger, but not with strong drink.
10 For the LORD has extended upon you the spirit of deep sleep and has closed your eyes: the prophets and your rulers, he has covered the seers with sleep.
11 And every vision is unto you as the words of a book that is sealed, which if it were delivered to one that knows how to read, saying, Read this, I pray thee: he shall say, I cannot; for it is sealed:
12 And if the book were delivered to him that does not know how to read, saying, Read this, I pray thee: he shall say, I do not know how to read.
