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).

sn The phrase in a son is the fulcrum of Heb 1:1-4. It concludes the contrast of God’s old and new revelation and introduces a series of seven descriptions of the Son. These descriptions show why he is the ultimate revelation of God.

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.

³ sn You founded the earth…your years will never run out. In its original setting Ps 102:25-27 refers to the work of God in creation, but here in Hebrews 1:10-12 the writer employs it in reference to Christ, the Lord, making a strong argument for the essential deity of the Son.

⁴ tc The words “like a garment” (ὡς ἱμάτιον, Jw" Jimation) are found in excellent and early mss (Ì⁴⁶ א A B D* 1739) though absent in a majority of witnesses (D¹ Ψ 0243 0278 33 1881 Ï lat sy bo). Although it is possible that longer reading was produced by overzealous scribes who wanted to underscore the frailty of creation, it is much more likely that the shorter reading was produced by scribes who wanted to conform the wording to that of Ps 102:26 (101:27 LXX), which here lacks the second “like a garment.” Both external and internal considerations decidedly favor the longer reading, and point to the author of Hebrews as the one underscoring the difference between the Son and creation.

sn The phrase like a garment here is not part of the original OT text (see tc note above); for this reason it has been printed in normal type.
