John Trapp on Isaiah 1:11

Ver. 11. To what purpoſe is the multitude of your ſacrifices] All which, without faith and devotion, are no better then meer hypocriſie and illuſion. It is, ſaith Oecolampadius, as if one ſhould preſent his Prince with many Carts laden with dirt: or as if good meat well-cooked ſhould be brought to Table by a naſty ſloven, who hath been tumbling in a jakes. They are your ſacrifices, and not mine: and though many and coſtly, yet I abhor ſuch ſacrificing Sodomites as you are, neither ſhall you be a button the better for your pompous he catombe and holocauſts. Your devotions are placed more in the maſſy materiality then inward purity, and therefore rejected. Go ye and learn what that is, I will have mercy (ſo, Faith, Repentance, new Obedience) and not ſacrifice, Mat. 9.14. You ſtick in the bark, reſt in the work done: your piety is potius in labris quam in fibris nata, a meer outſide, ſhels, Nut-kernels, ſhews and Pageants, not heart-workings, &c. Ʋna Dei eſt, purum, gratiſſima victima, pectus.

I am full of the burnt offerings] I am even cloyed and lothed with the ſight of them.

And of the fat of fed beaſts] Though ye bring the very beſt of the beſt; yet you do worſe then loſe your labour, caſt away your coſt: for therein ye commit ſin, Prov. 15.8. Diſpleaſing ſervice is double diſhonour, Deus homines iſtis, ut vocant, meritis praefidentes averſatur.

I delight not in the blood of Bullocks, &c.] He that killeth an Ox, unleſs withall he kill his corruptions, is as if he ſlew a man. He that ſacrificeth a Lamb, as if he cut off a dogs neck, &c. chap. 66.3. Thoſe miſcreants in Micah who offered largely for a Licenſe to live as they liſt, are rejected with ſcorn, Mic. 6 7.
