Hebrews 1:2

1:2 in these last days he has spoken to us in a son, ¹  whom he appointed heir of all things, and through whom he created the world. ² 

Hebrews 6:17

6:17 In the same way ³  God wanted to demonstrate more clearly to the heirs of the promise that his purpose was unchangeable, ⁴  and so he intervened with an oath,

Hebrews 11:7

11:7 By faith Noah, when he was warned about things not yet seen, with reverent regard ⁵  constructed an ark for the deliverance of his family. Through faith he condemned the world and became an heir of the righteousness that comes by faith.

[1:2]  ¹ tn The Greek puts an emphasis on the quality of God’s final revelation. As such, it is more than an indefinite notion (“a son”) though less than a definite one (“the son”), for this final revelation is not just through any son of God, nor is the emphasis specifically on the person himself. Rather, the focus here is on the nature of the vehicle of God’s revelation: He is no mere spokesman (or prophet) for God, nor is he merely a heavenly messenger (or angel); instead, this final revelation comes through one who is intimately acquainted with the heavenly Father in a way that only a family member could be. There is, however, no exact equivalent in English (“in son” is hardly good English style).

[1:2]  ² tn Grk “the ages.” The temporal (ages) came to be used of the spatial (what exists in those time periods). See Heb 11:3 for the same usage.

[6:17]  ³ tn Grk “in which.”

[6:17]  ⁴ tn Or “immutable” (here and in v. 18); Grk “the unchangeableness of his purpose.”

[11:7]  ⁵ tn Cf. BDAG 407 s.v. εὐλαβέομαι 2, “out of reverent regard (for God’s command).”
