Hebrews 10:28-29

A man who has gone against the law of Moses is put to death without pity on the word of two or three witnesses: But will not the man by whom the Son of God has been crushed under foot, and the blood of the agreement with which he was washed clean has been taken as an unholy thing, and who has had no respect for the Spirit of grace, be judged bad enough for a very much worse punishment?
