His watchmen are all blind, Without knowledge; They are all dumb dogs, They cannot bark; Raving, lying down, loving to slumber.
Targum Jonathan on Isaiah
Their watchmen are blind: they know nothing, all of them are dumb dogs, they are not able to bark, they are slumbering, they lie down, they love to sleep.
