Hebrews 10:26-29

King James Version

²⁶ For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,

²⁷ But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.

²⁸ He that despised Moses' law died without mercy under two or three witnesses:

²⁹ Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
