In this brief chapter Gurney deals with the relative clause in Hebrews 1:2: δι ου και τους αιωνας εποιησεν. He objects to one translation: “for whom also he constituted the ages.” He makes two points:
1) δια with the genitive case never refers to the final cause. This would require the accusative case. Instead, here it indicates agency: “by” or “through.”
2) αιωνας can be rendered as “ages” but it may also refer to the world or universe as it does in other Pauline passages (1 Tim 1:17; 1 Cor 2:7). Elsewhere in Hebrews (11:3) αιωνας clearly signifies the world or universe, and so it is likely that is the same meaning in 1:2. The Greek αιωνας corresponds to the Hebrew עלמ.
