Hebrews 2:10
Nestle 1904 Greek New Testament · Berean Standard Bible
Ἔπρεπεν γὰρ αὐτῷ δι’ ὃν τὰ πάντα καὶ δι’ οὗ τὰ πάντα πολλοὺς υἱοὺς εἰς δόξαν ἀγαγόντα τὸν ἀρχηγὸν τῆς σωτηρίας αὐτῶν διὰ παθημάτων τελειῶσαι
In bringing many sons to glory, it was fitting for God, for whom and through whom all things exist, to make the author (note: Or pioneer or founder) of their salvation perfect through suffering.
