What does Isaiah 1:11 mean?

'What do I care about all your sacrifices?' says the Lord. 'I've had enough of burnt offerings, rams, and the fat of well-fed animals. I don't want the blood of bulls, lambs, or goats.' Isaiah 1:11 - Modern Text Bible

(God rejects empty religious rituals, saying he doesn't want sacrifices from people whose hearts are far from him.)
