Hebrews 6:16

for confirmation--not to be joined, as English Version, to "an oath"; but to "an end" [ALFORD]. I prefer, "The oath is to them, in respect to confirmation (of one's solemn promise or covenant; as here, God's), an end of all contradiction (so the Greek is translated, Heb 12:3), or "gainsaying." This passage shows: (1) an oath is sanctioned even in the Christian dispensation as lawful; (2) that the limits to its use are, that it only be employed where it can put an end to contradiction in disputes, and for confirmation of a solemn promise.

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).

6:16 It is a general principle in human relationships that when people take an oath, the oath is binding. If in human contexts oaths give assurance that something is true, an oath from God ought to inspire much greater confidence (6:17-19). • someone greater than themselves: Cp. 6:13.
