Hebrews 10:27-31

27but a certain fearful expectation of judgment, and heat of fire about to devour the adversaries.

28Any one that has disregarded Moses' law dies without mercy on [the testimony of] two or three witnesses:

29of how much worse punishment, think ye, shall he be judged worthy who has trodden under foot the Son of 1God, and esteemed the blood of the covenant, whereby he has been sanctified, common, and has insulted the Spirit of grace?

30For we know him that said, To me [belongs] vengeance; I will recompense, saith the Lord: and again, The Lord shall judge his people.

31[It is] a fearful thing falling into [the] hands of [the] living 2God.
