Isaiah 56:10-11

10Israel's guards are blind! They do not see what is happening. They are all like dogs that cannot make a noise. They cannot warn people about danger. They love to lie on the ground and they dream while they sleep.

11They are like dogs who are always hungry. They eat a lot but they never have enough. They are like shepherds who do not understand what to do. They do whatever they want to do, so that it will help them get what they want.
