LXX2012(i)
10 For the Lord has made you to drink a spirit of deep sleep; and he shall close their eyes, and [the eyes] 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 can’t read [it], for it is sealed.
