John Trapp on Isaiah 56:11

Ver. 11. Yea they are greedy dogs that can never have enough] Heb. ſtrong of ſoul, or of appetite, they know not to be ſatisfied. Lac & lana is that they look for; the inſtruments of a fooliſh ſhepherd, forcipes & mulctra, the ſheares and milk paile are in their hand, Zach. 11.15. they eat the fruit and drink the milk, as Ezek 25.4. yea they eat the fat, and tear the claws in pieces, Zach. 11.16. Albertus Magnus complained heavily of the covetouſneſs of Paſtours in his time: In Mat. 10.16. Temporalia colligunt perſe, ſpiritualia ſeminant per alios, ſaith he; they take little paines, but care not how much profit they make: he that made Faſciculus temporum, doth the like. Another modern writer fitly applyeth that to them, which Oedipus in Sophocles ſaith of Tireſias the Heathen-Prophet, — [non-Latin text not transcribed] [non-Latin text not transcribed]. i. e. that he looked only to his gain, but was little ſeen in his profeſſion. Such a one was Balaam, Jude 11. ſuch were thoſe falſe Prophets, Ezek. 13. the covetous Phariſees, Luke 16.14. the falſe Apoſtles, Rom. 16.18. called dogs, Phil. 3.2. ſuch as had a greedy worm under their tongues, and could never be ſatisfied.

And they are ſhepherds that cannot underſtand] The duſt of covetouſneſſe hath even put out their eyes: Midas ſecundum Etymologi[illegible: 1 letter]m Graecam coecus eſt. as it fared with the blind and greedy Phariſees, Avidi à non videndo: the world is a pearle in their eyes, they cannot ſee God, nor skill of their office. Tremellius rendreth it neſciunt docere, they know not to teach, as being choaked haply with a fat benefice; a common practice of the Pope.

They all look to their own way] Mind their own commodity, whereby they are led up and down, as an Ox may be all a ground over, by a bottle of hay.
