What country’s shepherds went to sleep while on duty and let the flock get scattered?

Answer:

Good question.

It was Israel who the Lord rebuked:  Jeremiah 23:2  Therefore thus saith the LORD God of Israel against the pastors that feed my people; Ye have scattered my flock, and driven them away, and have not visited them: behold, I will visit upon you the evil of your doings, saith the LORD.
