Hebrews 2:16

Here "the seed of Abraham" probably refers primarily to believers, the spiritual descendants of Abraham (Galatians 3:29), rather than to Jews, the physical descendants of Abraham (cf. Isaiah 41:8-10). The original readers, saved Jews, were both the physical and spiritual descendants of Abraham. The contrast is between angelic and human believers in the context. Jesus Christ does not give help to angels in the same way He gives help to Christians. He helps us uniquely as an elder brother and parent (Hebrews 2:11-15), a fellow human being.
