The pastors are become brutish; not that the prophet takes off all blame from the people, but that he layeth it chiefly upon the rulers of church and state; for so is pastor taken frequently. See Jeremiah 23:1-3, And have not sought the Lord; not sought unto him, and taken him into their counsels. Therefore they shall not prosper: the prophet gives the reason why nothing went well with them, namely, because there was no regard had to godliness, without which we cannot expect a blessing upon any thing. All their flocks shall be scattered, i.e. all that have been committed to their care shall be carried unto Babylon, and divers of them dispersed abroad into several countries for their sakes.
