Leviticus 7:27

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?

For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto the LORD, even the soul that eateth it shall be cut off from his people.
