Did you read the next chapter, brother.
Hebrews 10:26-28 NKJV - For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. Anyone who has rejected Moses’ law(Torah/Instructions) dies without mercy on the testimony of two or three witnesses.
Hey my friend, I read and believe all of the Bible.
