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).
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 tn Grk “who being…and sustaining.” Heb 1:1-4 form one skillfully composed sentence in Greek, but it must be broken into shorter segments to correspond to contemporary English usage, which does not allow for sentences of this length and complexity.
4 tn Grk “by the word of his power.”
5 sn An allusion to Ps 110:1, quoted often in Hebrews.
