Isaiah 66:3

[The acts of the hypocrite''s worship are as abominable to God as if they were offered to idols.] He who kills an ox [then] will be as guilty as if he slew and sacrificed a man; he who sacrifices a lamb or a kid, as if he broke a dog''s neck and sacrificed him; he who offers a cereal offering, as if he offered swine''s blood; he who burns incense [to God], as if he blessed an idol. [Such people] have chosen their own ways, and they delight in their abominations;
