Esias 29:10

10 For the Lord has made you to drink a spirit of deep sleep; and he shall close their eyes, and of their prophets and of their rulers, who see secret things.

Esias 29:10 In-Context

8 And as men drink and eat in sleep, and when they have arisen, the dream is vain: and as a thirsty man dreams as if he drank, and having arisen is still thirsty, and his soul has desired in vain: so shall be the wealth of all the nations, as many as have fought against the mount Sion.
9 Faint ye, and be amazed, and be overpowered, not with strong drink nor with wine.
10 For the Lord has made you to drink a spirit of deep sleep; and he shall close their eyes, and of their prophets and of their rulers, who see secret things.
11 And all these things shall be to you as the words of this sealed book, which if they shall give to a learned man, saying, Read this, he shall then say, I cannot read , for it is sealed.
12 And this book shall be given into the hands of a man that is unlearned, and shall say to him, Read this; and he shall say, I am not learned.
