Hebrews 6:17

Wherein--that is, Which being the case among men, God, in accommodation to their manner of confirming covenants, superadded to His sure word His oath: the "TWO immutable things" (Heb 6:18). willing . . . counsel--Greek, "willing . . . will"; words akin. Expressing the utmost benignity [BENGEL]. more abundantly--than had He not sworn. His word would have been amply enough; but, to make assurance doubly sure, He "interposed with an oath" (so the Greek). Literally, He acted as Mediator, coming between Himself and us; as if He were less, while He swears, than Himself by whom He swears (for the less among men usually swear by the greater). Dost thou not yet believe, thou that hearest the promise? [BENGEL]. heirs of promise--not only Abraham's literal, but also his spiritual, seed (Gal 3:29).

In this chapter the apostle proceeds to persuade the Hebrews to make a better proficiency in religion than they had done, as the best way to prevent apostasy, the dreadful nature and consequences of which sin he sets forth in a serious manner (Heb 6:1-8), and then expresses his good hopes concerning them, that they would persevere in faith and holiness, to which he exhorts them, and sets before them the great encouragement they had from God, both with respect to their duty and happiness (Heb 6:9 to the end).

6:17-18 God also bound himself with an oath: See 7:20-22. God’s oath makes it clear that he would never change his mind . . . because it is impossible for God to lie (see Ps 110:4). • We have fled to him for refuge, like those in the Old Testament era who killed someone accidentally (Num 35:9-34; Deut 4:41-43); Christ is like a city of refuge, where believers escape God’s wrath. Christ’s followers, therefore, have great confidence.
