Hebrews 10:26-29

UKJV(i) 26 For if we sin willfully after that we have received the knowledge of the truth, there remains 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 greater punishment, suppose all of you, shall he be thought worthy, who has trodden under foot the Son of God, and has counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and has done despite unto the Spirit (o. pneuma) of grace?
