A Spirit of Slumber
"According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear, unto this day" (Romans 11:8).
"For the Lord hath poured out upon you the Spirit of deep sleep, and hath closed your eyes: the prophets and your leaders, the seers hath he covered. And the vision of all is become unto you as the words of a book that is sealed" (Isaiah 29:10-11).
