Matthew Poole and continuators on Isaiah 1:11

11 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.

They are vain and useless, being neither accepted by me, nor beneficial to you.

Who am a Spirit, and therefore cannot be satisfied with such carnal Oblations, but expect to be worshipped in spirit and truth, and to have your Hearts and Lives, as well as your Bodies and Sacrifices, presented unto me.

I am glutted with them, and therefore loath them.

He mentions the fat and blood, because these were in a peculiar manner reserved for God, Levit. 3. 15, 16 & 17. 11. to intimate, that even the best of their Sacrifices were rejected by him.
