Isaiah 66:3

He that killeth an ox [is as if] he (d) slew a man; he that sacrificeth a lamb, [as if] he cut off a dog's neck; he that offereth an oblation, [as if he offered] swine's blood; he that burneth incense, [as if] he blessed an idol. Yea, they have chosen their own ways, and their soul delighteth in their abominations.

(d) Because the Jews thought themselves holy by offering their sacrifices, and in the mean season had neither faith or repentance, God shows that he no less detests these ceremonies than he does the sacrifices of the heathen, who offered men, dogs and swine to their idols, which things were expressly forbidden in the law.
