What does Hosea 9:4 mean?

They won't pour out wine offerings to the Lord or make sacrifices pleasing to Him. Their food will be like funeral bread—anyone who eats it will be defiled. None of it will come into the Lord's house. Hosea 9:4 - Modern Text Bible

(In exile, Israel can't worship God as they should. Their rituals become meaningless, and their separation from God is complete.)
