Isaiah 56:10 in the King James Version
His watchmen are blind: they are all ignorant, they are all dumb dogs, they cannot bark; sleeping, lying down, loving to slumber.
Context
9 All you animals of the field, come to devour, all you animals in the forest.
10 His watchmen are blind. They are all without knowledge. They are all mute dogs. They can’t bark— dreaming, lying down, loving to slumber.
11 Yes, the dogs are greedy. They can never have enough. They are shepherds who can’t understand. They have all turned to their own way, each one to his gain, from every quarter.
