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. To what purpose, etc. "What have I to do" - The prophet Amos has expressed the same sentiments with great elegance: -
I hate, I despise your feasts;
And I will not delight in the odour of your solemnities:
Though ye offer unto me burnt-offerings
And your meat-offerings, I will not accept:
Neither will I regard the peace-offerings of your fatlings.
Take away from me the noise of your songs;
And the melody of your viols I will not hear.
But let judgment roll down like waters;
And righteousness like a mighty stream.
