him--God, who enters no empty threats. Vengeance belongeth unto me--Greek, "To Me belongeth vengeance": exactly according with Paul's quotation, Rom 12:19, of the same text.

The apostle knew very well that the Hebrews, to whom he wrote, were strangely fond of the Levitical dispensation, and therefore he fills his mouth with arguments to wean them from it; and in order thereto proceeds in this chapter, I. To lay low the whole of that priesthood and sacrifice (Heb 10:1-6). II. He raises and exalts the priesthood of Christ very high, that he might effectually recommend him and his gospel to them (Heb 10:7-18). III. He shows to believers the honours and dignities of their state, and calls them to suitable duties (Heb 10:19 to the end).

10:30-31 “The Lord will judge his own people”: Deut 32:36; cp. 1 Pet 4:17-18. • That God will pay them back and will judge his own people shows the dreadful circumstances of those who have rejected Christ. Once God moves to judge a person, no one can rescue that person out of God’s hand (Deut 32:39).
