ISB ~ Hebrews 2 v16

descendants of Abraham:This could be taken in a biological sense, referring to the family of Israel descended from Abraham, or, more likely, in a Christian sense of the family of Jews and Gentiles who together imitate the faith of Abraham (Rom 4:9-13) and inherit the blessings that Yahweh pledged to the patriarch by oath (Gen 22:16-18; Gal 3:6-29). Either way, the point is that Jesus came to rescue, not angels, but fallen men.
