Hebrews 10:4

10:4 For the blood of bulls and goats cannot take away sins.

Hebrews 10:10-17

10:10 By his will we have been made holy through the offering of the body of Jesus Christ once for all. 10:11 And every priest stands day after day serving and offering the same sacrifices again and again – sacrifices that can never take away sins. 10:12 But when this priest had offered one sacrifice for sins for all time, he sat down at the right hand of God, 10:13 where he is now waiting until his enemies are made a footstool for his feet. 10:14 For by one offering he has perfected for all time those who are made holy. 10:15 And the Holy Spirit also witnesses to us, for after saying, 10:16 “This is the covenant that I will establish with them after those days, says the Lord. I will put my laws on their hearts and I will inscribe them on their minds,” 10:17 then he says, “Their sins and their lawless deeds I will remember no longer.”
