Here's chapter XIV, in which we are told to do a heckin' sacrifice - because Hebrews must have lied about there not being sacrifices anymore or something.
"1. And on the Lord's Day of the Lord come together, and break bread, and give thanks, having before confessed your transgressions, that your sacrifice may be pure.
2. Let no one who has a dispute with his fellow come together with you until they are reconciled, that your sacrifice may not be defiled.
3. For this is that which was spoken by the Lord: "In every place and time offer me a pure sacrifice, for I am a great King, saith the Lord, and my name is wonderful among the Gentiles."
