Hebrews 10:28 - Ellicott's Commentary On The Whole Bible

He that despised Moses’ law. — Rather, A man that hath set at nought a law of Moses dieth without pity before two or three witnesses. The reference is to Deuteronomy 17:2-7, the last words being a direct quotation from Hebrews 10:6 in that section. There the subject is apostasy from Jehovah to the worship of idols. That sin which, by the acknowledgment of all, had in ancient time robbed Israel of the name of God’s people is tacitly placed by the side of the sin of those who for sake Christ. It will be seen how impressively the thought of the last verse is maintained in this.
