These two chapters present the ultimate transition from Judaism to Christianity. The Lord's perfect sacrifice as the Lamb of God is seen as the fulfilment of all the Old Testament sacrifices in the Judaic system. With this fulfilment, there would no longer be a need for those Jewish sacrifices to continue. Hence, that whole sacrificial system would be consequently set aside (Heb. 10:1-18). There is now no longer a need for an "offering for sin" after the old order under the Law (Heb. 10:18).
