John Trapp on Isaiah 66:3

Ver. 3. He that killeth an Ox, is as if he ſlew a Man] Unleſs, together with his Ox, he kill his corruptions, and lay faſt hold upon Chriſt (who himſelf wa ſacrificed for us, 1 Cor. 5.7.) by a lively faith. Heathens ſacrificed men to Saturn: dogs alſo and ſwine and other unclean creatures to their other dunghil-dieties. Maſs-prieſts do the like by their cruelty, hypocriſy, idolatry, impudency, luxury: their prayers therefore, faſtings, pennances, pilgrimages, &c. are diſaccepted.

He that ſacrificeth a Lamb] Unleſs withal he ſacrifice his luſts, and look to the Lamb of God, ſlain from the beginning of the world, &c.

As if he cut off a dogs neck] Heb. as if he necked a dog, that is, decolled him, beheaded him for ſacrifice: this was abſolutely forbidden, Deut. 23.18. Excerebraret. Vulg. Plut. [non-Latin text not transcribed], The Athenians alſo ſuffered not a dog to enter into their Tower dedicated to Minerva, for his heat in Venery and ill ſavour, ſaith Plutarch.

He that offereth an oblation] Unleſs withal he preſent his body for a ſacrifice holy and acceptable unto God, as Rom. 12.1.

Is as if he offered ſwines blood] Blood was not to be offered at all in an oblation or meat-offering, but meal, oyle, wine, Levit. 2. much leſs ſwines blood. See Levit. 11.7.

He that burneth incenſe] In honour of me, unleſs his heart aſcend up withal in thoſe pillars of ſweet ſmoke, as Manoahs Angel did in the ſmoke of the ſacrifice.

Is as if he bleſſed an Idol] i. e. Gave thankes to an Idol (called here by a name that ſignifyeth vanity or vexation) as if he were a God: in doing whereof, God holdeth himſelf leſs diſhonoured, then by their hypocritical ſervices performed to himſelf, Ezek. 20.39.

Be[illegible: 1 letter]n. Yea they have choſen their own wayes] Which muſt needs be naught: Nemo ſibi de ſuo palpet: Are ye not carnal and walk as men, ſaith Paul; that is, as naughty men? Horreo quicquid de meo eſt, ut meus ſim.
