John 10:12

But the hireling — It is not the bare receiving hire, which denominates a man a hireling: (for the labourer is worthy of his hire; Jesus Christ himself being the Judge: yea, and the Lord hath ordained, that they who preach the Gospel, should live of the Gospel:) but the loving hire: the loving the hire more than the work: the working for the sake of the hire. He is a hireling, who would not work, were it not for the hire; to whom this is the great (if not only) motive of working. O God! If a man who works only for hire is such a wretch, a mere thief and a robber, what is he who continually takes the hire, and yet does not work at all? The wolf — signifies any enemy who, by force or fraud, attacks the Christian's faith, liberty, or life. So the wolf seizeth and scattereth the flock — He seizeth some, and scattereth the rest; the two ways of hurting the flock of Christ.
