Zechariah 11:17: Who is the idol shepherd? who

Who is the idol shepherd? who
The slighted flock of Jesus leaves?
The man that steals his Saviour's due
And human praise with joy receives:
The charge of souls he undertakes;
But when the streams of trouble rise.
He sees the wolf, the sheep forsakes,
And basely as an hireling flies.

Justice Divine with sharpest sword,
His arm and his right eye shall smite;
(Hear this, ye traitors to your Lord;)
Bereave him of his i)owcr and light:
Soon as the threaten'd curse takes place
The wietch receives his instant doom;
Wither'd is all his strength of grace.
And all his light is hellish gloom.
Lord, help me that I never may
My gracious power and knowledge lose;
But meekly with Thy people stay,
Their burden bear, their praise refuse.
