Isaiah 29:10

10 For the Lord has poured out on you
a strong urge to sleep deeply.
Heb “a disposition [or “spirit”] of deep sleep.” Through this mixed metaphor (sleep is likened to a liquid which one pours and in turn symbolizes spiritual dullness) the prophet emphasizes that God himself has given the people over to their spiritual insensitivity as a form of judgment.

He has shut your eyes (the prophets),
and covered your heads (the seers).
