'Slaughtered' in the Bible

So God turned away from them and gave them over to worship the heavenly bodies. As it is written in the book of the Prophets: "O house of Israel, you didn't offer me slaughtered animals and sacrifices those 40 years in the wilderness, did you?

This was the passage of Scripture he was reading: "Like a sheep he was led away to be slaughtered, and like a lamb is silent before its shearer, so he does not open his mouth.
