Malachi

To what purpose is the multitude of your sacrifices unto me? saith the Lord: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats.

And when ye spread forth your hands, I will hide mine eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood.

And Aaron said unto Moses, Behold, this day have they offered their sin offering and their burnt offering before the Lord; and such things have befallen me: and if I had eaten the sin offering to day, should it have been accepted in the sight of the Lord?

Wherefore the sin of the young men was very great before the Lord: for men abhorred the offering of the Lord.
