Read Isaiah 56:11 Using Other Translations
Yea, they are greedy dogs which can never have enough, and they are shepherds that cannot understand: they all look to their own way, every one for his gain, from his quarter.
The dogs have a mighty appetite; they never have enough. But they are shepherds who have no understanding; they have all turned to their own way, each to his own gain, one and all.
Like greedy dogs, they are never satisfied. They are ignorant shepherds, all following their own path and intent on personal gain.
